How to use Event Viewer on Windows 10

If Windows 10 or an app isn't behaving as expected, you can use the Event Viewer to understand and troubleshoot the issue, and in this guide, we'll show you how.

Windows 10 Event Viewer

On Windows 10, the Event Viewer is a handy legacy tool designed to aggregate event logs from apps and system components into an easily digestible structure, which you can then analyze to troubleshoot and fix software or hardware problems with your computer.

Typically, most users don't use or know about the Event Viewer. However, it should be the first place to check to troubleshoot problems since virtually every hardware failure, app crash, driver malfunction, system issue, security access, and events from apps and services working without issues, will be recorded in this database.

If your device is suddenly rebooting without reason, freezing up, drivers aren't behaving as expected, or you're experiencing Blue Screen of Death (BSoD) , the Event Viewer on Windows 10 may contain logs with the information you need to resolve the problem or at least find out clues to help you find a solution.

In this Windows 10 guide, we'll walk you through the steps to navigate and use the Event Viewer on your device.

On Windows 10, the Event Viewer exists to help you monitor apps and system components as well as troubleshoot problems.

Interface navigation

To open the Event Viewer on Windows 10, simply open start and perform a search for Event Viewer , and click the top result to launch the console.

The experience is divided into four main groups, including "Custom Views," "Windows Logs," "Applications and Services Logs," and "Subscriptions," and each group stores related logs.

Although each group can hold different app and system logs, most of the time, you'll only be analyzing the Application , Security , and System logs inside the "Windows Logs" group to investigate an issue.

Inside "Application," you'll find events about the interface and other essential components to run an app. In the "Security" category that's where the logs events related to login attempts and security features are grouped, and the "System" category records the logs related to apps installed on Windows 10.

The Event Viewer can track three kinds of event levels, including Error , Warning , and Information . The "Error" logs, as the name implies, indicate problems that require immediate attention. The "Warning" logs are not necessarily significant. However, they might signal that something is not working as expected, and the "Information" logs are simply events that record normal operation of apps and services.

Usually, all apps should log events in this database, but it's not always true for many third-party applications.

If the device is working normally, you will still see errors and warnings, but they'd likely not be anything concerning. For example, sometimes, you may see an error if a service couldn't load at startup, but it restarted at a later time normally. The time service couldn't synchronize correctly, Windows 10 couldn't access a file on a network shared folder because there was a connection problem — or an app suddenly crashed, but then you opened it again, and it continued to work without issues.

While in the console, you can select one of the main groups to view additional information, such as the number of events and size on disk for each view. Or you can select "Event Viewer" from the top-left to get an overview and summary events, recently view notes, and log summary.

If you select one of the groups, on the right side, you'll see all the events with their "Level" information, "Date and Time" of creation, "Source," and "Event ID," and "Task Category." If you want to see more details, you can select the event, and the information will be displayed at the bottom of the console, or you can double-click the event to access more details.

In the event properties window, the "General" tab includes an easy-to-understand description of the error, warning, or information.

Usually, the description should give you enough information to understand and resolve the issue. However, the "Event ID" is also an important piece of information, as you can use it to search online to find out more information, and possible instructions to fix the problem.

Search for specific logs

If you're looking for a specific event, the console provides at least two ways to find events using the filters or keyword search.

Advanced search

To use the filters to find a specific type of log, use these steps:

  • Open Start .
  • Search for Event Viewer and select the top result to open the console.
  • Expand the event group.
  • Right-click a category and choose the Filter Current Log option. Quick note: You can also access the filter and other common options in the Action pane available in the right side of the console.
  • Click the Filter tab.
  • Last 12 hours.
  • Last 24 hours.
  • Last 7 days.
  • Last 30 days.
  • Custom range.
  • Information.
  • (Optional) Select the event sources. This can be from one or more apps and services.
  • (Optional) Select the Task category .
  • (Optional) Select or confirm a keyword to help narrow down the log.
  • Use the default selections for User and Computers .
  • Click the OK button.

Once you complete the steps, related logs will appear filtered in the console. If you want to clear the current filter, right-click the group, and select the Clear Filter option.

Basic search

To use a keyword to find an error, warning, or information event with Event Viewer, use these steps:

  • Expand the event groups.
  • Right-click a category and choose the Find option.
  • Type a keyword and press the Find Next button.

After you complete the steps, the event will be highlighted in the list if a match is found.

Create custom views

In the case that you frequently search for the same type of events, the Event Viewer also comes with an option to create custom views to quickly filter the logs to view only those that are relevant to you.

To create a custom view in the Event Viewer, use these steps:

  • Right-click a category and choose the Create Custom View option.
  • Use the "Logged" drop-down menu and select a time range.
  • Select the By log option.
  • Use the "Event logs" drop-down menu and select the event category you want to filter. For example, System .
  • Select or confirm a keyword to help narrow down the log.
  • Confirm a name for the custom view.
  • (Optional) Compose a description for the custom view.
  • Select where to save the view. Quick note: The default location is always recommended, but you can always create a new folder to store them.

Once you complete the steps, the next time you need to view specific logs, you can expand the "Custom Views" folder and select the view you created.

Clear log history

On Windows 10, logs help you track your device's health and troubleshoot problems, and you should keep them as long as possible. However, you can clear the log history to free up space or make it easier to track an existing problem.

To clear the log history of a particular category, use these steps:

  • Right-click a category, and select the Clear Log option.
  • Click the Clear button. Quick note: If you want to archive the log history on a file outside the Event Viewer, you can also click the Save and Clear button.

After you complete the steps, the events will be deleted, and the console will start recording new events.

windows task scheduler event on external ip change

UPDATE 2 : i came up with this script :

the issue is that the script Established_SSH.bat would not run it would run the first one but not the second one the content of the first script is :

I'm again looking forward to you for a way around this

UPDATE : now i have created two simple script that log my external ip to two different files in the same directory how could i compare the value of these and if they don't match then run my script ?

i'm looking for the log that windows create if it even does. When an external IP change on my computer, i'm on windows 10 pro. Basically right now the solution i've been trying is to set that :

1

well that was supposed to monitor and give log when my external ip changes but in fact it just create a log every 10 minutes for some reason like that :

2

so i'm looking forward to you if by any chance you can help me around with that thanks.

ps : if you need further info just ask ;) ps* : this event will just trigger two simple script.

  • 1 Windows doesn’t know the external IP, therefore you can’t trap it for task scheduler. You’ll need to run a script or app every X that looks up the external ip via an external service such as whatismyip.com’ API and compares it to the result last time. –  Tyson Apr 23, 2018 at 1:59
  • I understand the principle of that, but if you could lead me to the solution it would be nice. Since the idea of scripting that sort of things is unclear, i think the biggest issue is not the tracking and comparing maybe a bit. but it's rather how do i trigger event to happen in windows task scheduler with a script as an event –  argaud bastien Apr 23, 2018 at 15:09
  • See community.spiceworks.com/topic/… –  Tyson Apr 23, 2018 at 15:14
  • thanks for that something they don't talk about is how to input the result into a log automatically and then the whole work around comparing the result also i'm sorry to annoy you with such dull question –  argaud bastien Apr 23, 2018 at 15:26
  • and my problem is I don’t know how to do it in windows.. I can do it in bash.... –  Tyson Apr 23, 2018 at 15:33

so I found my way around i just simplified the script to that one

so I came to realise that the command

will shut down the connection between me and the VPS so it would while the script automatically.

thanks to tyson for his guidance :)

Get-Event Log

Gets the events in an event log, or a list of the event logs, on the local computer or remote computers.

Description

The Get-EventLog cmdlet gets events and event logs from local and remote computers. By default, Get-EventLog gets logs from the local computer. To get logs from remote computers, use the ComputerName parameter.

You can use the Get-EventLog parameters and property values to search for events. The cmdlet gets events that match the specified property values.

PowerShell cmdlets that contain the EventLog noun work only on Windows classic event logs such as Application, System, or Security. To get logs that use the Windows Event Log technology in Windows Vista and later Windows versions, use Get-WinEvent .

Get-EventLog uses a Win32 API that is deprecated. The results may not be accurate. Use the Get-WinEvent cmdlet instead.

Example 1: Get event logs on the local computer

This example displays the list of event logs that are available on the local computer. The names in the Log column are used with the LogName parameter to specify which log is searched for events.

The Get-EventLog cmdlet uses the List parameter to display the available logs.

Example 2: Get recent entries from an event log on the local computer

This example gets recent entries from the System event log.

The Get-EventLog cmdlet uses the LogName parameter to specify the System event log. The Newest parameter returns the five most recent events.

Example 3: Find all sources for a specific number of entries in an event log

This example shows how to find all of the sources that are included in the 1000 most recent entries in the System event log.

The Get-EventLog cmdlet uses the LogName parameter to specify the System log. The Newest parameter selects the 1000 most recent events. The event objects are stored in the $Events variable. The $Events objects are sent down the pipeline to the Group-Object cmdlet. Group-Object uses the Property parameter to group the objects by source and counts the number of objects for each source. The NoElement parameter removes the group members from the output. The Sort-Object cmdlet uses the Property parameter to sort by the count of each source name. The Descending parameter sorts the list in order by count from highest to lowest.

Example 4: Get error events from a specific event log

This example gets error events from the System event log.

The Get-EventLog cmdlet uses the LogName parameter to specify the System log. The EntryType parameter filters the events to show only Error events.

Example 5: Get events from an event log with an InstanceId and Source value

This example gets events from the System log for a specific InstanceId and Source.

The Get-EventLog cmdlet uses the LogName parameter to specify the System log. The InstanceID parameter selects the events with the specified Instance ID. The Source parameter specifies the event property.

Example 6: Get events from multiple computers

This command gets the events from the System event log on three computers: Server01, Server02, and Server03.

The Get-EventLog cmdlet uses the LogName parameter to specify the System log. The ComputerName parameter uses a comma-separated string to list the computers from which you want to get the event logs.

Example 7: Get all events that include a specific word in the message

This command gets all the events in the System event log that contain a specific word in the event's message. It's possible that your specified Message parameter's value is included in the message's content but isn't displayed on the PowerShell console.

The Get-EventLog cmdlet uses the LogName parameter to specify the System event log. The Message parameter specifies a word to search for in the message field of each event.

Example 8: Display the property values of an event

This example shows how to display all of an event's properties and values.

The Get-EventLog cmdlet uses the LogName parameter to specify the System event log. The Newest parameter selects the most recent event object. The object is stored in the $A variable. The object in the $A variable is sent down the pipeline to the Select-Object cmdlet. Select-Object uses the Property parameter with an asterisk ( * ) to select all of the object's properties.

Example 9: Get events from an event log using a source and event ID

This example gets events for a specified Source and Event ID.

The Get-EventLog cmdlet uses the LogName parameter to specify the Application event log. The Source parameter specifies the application name, Outlook. The objects are sent down the pipeline to the Where-Object cmdlet. For each object in the pipeline, the Where-Object cmdlet uses the variable $_.EventID to compare the Event ID property to the specified value. The objects are sent down the pipeline to the Select-Object cmdlet. Select-Object uses the Property parameter to select the properties to display in the PowerShell console.

Example 10: Get events and group by a property

The Get-EventLog cmdlet uses the LogName parameter to specify the System log. The UserName parameter includes the asterisk ( * ) wildcard to specify a portion of the user name. The event objects are sent down the pipeline to the Group-Object cmdlet. Group-Object uses the Property parameter to specify that the UserName property is used to group the objects and count the number of objects for each user name. The NoElement parameter removes the group members from the output. The objects are sent down the pipeline to the Select-Object cmdlet. Select-Object uses the Property parameter to select the properties to display in the PowerShell console.

Example 11: Get events that occurred during a specific date and time range

This example gets Error events from the System event log for a specified date and time range. The Before and After parameters set the date and time range but are excluded from the output.

The Get-Date cmdlet uses the Date parameter to specify a date and time. The DateTime objects are stored in the $Begin and $End variables. The Get-EventLog cmdlet uses the LogName parameter to specify the System log. The EntryType parameter specifies the Error event type. The date and time range is set by the After parameter and $Begin variable and the Before parameter and $End variable.

Gets events that occurred after a specified date and time. The After parameter date and time are excluded from the output. Enter a DateTime object, such as the value returned by the Get-Date cmdlet.

-AsBaseObject

Indicates that this cmdlet returns a standard System.Diagnostics.EventLogEntry object for each event. Without this parameter, Get-EventLog returns an extended PSObject object with additional EventLogName , Source , and InstanceId properties.

To see the effect of this parameter, pipe the events to the Get-Member cmdlet and examine the TypeName value in the result.

Indicates that this cmdlet returns the output as strings, instead of objects.

Gets events that occurred before a specified date and time. The Before parameter date and time are excluded from the output. Enter a DateTime object, such as the value returned by the Get-Date cmdlet.

-ComputerName

This parameter specifies a remote computer's NetBIOS name, Internet Protocol (IP) address, or a fully qualified domain name (FQDN).

If the ComputerName parameter isn't specified, Get-EventLog defaults to the local computer. The parameter also accepts a dot ( . ) to specify the local computer.

The ComputerName parameter doesn't rely on Windows PowerShell remoting. You can use Get-EventLog with the ComputerName parameter even if your computer is not configured to run remote commands.

Specifies, as a string array, the entry type of the events that this cmdlet gets.

The acceptable values for this parameter are:

  • Information
  • FailureAudit
  • SuccessAudit

Specifies the index values to get from the event log. The parameter accepts a comma-separated string of values.

-InstanceId

Specifies the Instance IDs to get from the event log. The parameter accepts a comma-separated string of values.

Displays the list of event logs on the computer.

Specifies the name of one event log. To find the log names use Get-EventLog -List . Wildcard characters are permitted. This parameter is required.

Specifies a string in the event message. You can use this parameter to search for messages that contain certain words or phrases. Wildcards are permitted.

Begins with the newest events and gets the specified number of events. The number of events is required, for example -Newest 100 . Specifies the maximum number of events that are returned.

Specifies, as a string array, sources that were written to the log that this cmdlet gets. Wildcards are permitted.

Specifies, as a string array, user names that are associated with events. Enter names or name patterns, such as User01 , User* , or Domain01\User* . Wildcards are permitted.

You cannot pipe input to Get-EventLog .

System.Diagnostics.EventLogEntry. System.Diagnostics.EventLog. System.String

If the LogName parameter is specified, the output is a collection of System.Diagnostics.EventLogEntry objects.

If only the List parameter is specified, the output is a collection of System.Diagnostics.EventLog objects.

If both the List and AsString parameters are specified, the output is a collection of System.String objects.

The cmdlets Get-EventLog and Get-WinEvent are not supported in the Windows Preinstallation Environment (Windows PE).

Windows System Event log reports nother computer is using my IP in this network

Original title: Windows System Event log reported me an error

I have been notified that another computer is using my IP in this network, I need you to help me solving this situation as soon as possible

Thanks a lot

Hi Dr. JesusMejia,

1. What is the complete error message that you receive?

2. What is the make and model of the PC?

3. Do you have another computer connected to the same network?

4. Who is your Internet Service Provider(ISP)?

If you are getting an error message 'Windows has detected an IP address conflict' 'Another computer on this network has the same IP address as this computer', then it means that means more than one computer is using the same IP address, which is resulting in a conflict.

Each computer on a network must have a unique IP address.

I would suggest you to follow these methods and check if it helps. Method 1: To fix this problem, run the Network troubleshooter. Follow steps from this article: Get help with "There is an IP address conflict" message

If that does not help, release and renew the IP address computers with the same IP address.

To do this, follow these steps:

a. Click on Start. In the Start   search box, type cmd . Right-click on cmd.exe and choose Run as administrator .

b. In the prompt, type ipconfig and press Enter key .

c. Type ipconfig /release (note the space between ipconfig and /) and press Enter.

The IP configuration information will refresh. You should see your IP address change to 0.0.0.0.

d. Type ipconfig /renew  (note the space between ipconfig and /) and press Enter.

The DHCP configuration for all adapters will be renewed. To renew the IP address for a specific adapter, type the adapter name that appears when you type ipconfig at the command prompt.

Your computer will attempt to obtain a new IP address from the network. This may take a few minutes.

If this process is successful, you will see a new IP address listed when the IP configuration information refreshes.

Let us know if it helps. If the issue persists, we would be glad to assist you further.

Hi Cynthia,

Have you tried the suggestions proposed in my first response?

If you're on a home network, reboot all the computers and the router it will straighten itself out unless you are running static IP. 

Assign an IP address manually and see if that fixes the issue.

Follow these steps:

a. Click “Start” and click “Control Panel”.

b. In the search box type “Network and sharing”.

c. From the search results, click “Network and Sharing Center”.

d. On the left hand side, click “Change adapter settings.”

e. Right-click the connection and click “Properties”.

f. Select “Internet Protocol Version 4 (TCP/IPV4)” and click “Properties.”

g. Under “General” tab, select to check “Use the following IP address.”

Manually assign an IP address which is different from that of the other computer

Security Log in Event Viewer does not store IPs

I'd like to write a service that pulls Event Viewer records, specifically from the Security log. Of particular interest to me are things like event id 4625 (audit fail) messages. Ideally I'd like to store the IP of clients that cause audit fails more than n times in m seconds for some amount of time.

Sounds easy enough, so I quickly whipped up a .NET service to do just this. However, when I pull these audit failures, the "Source Network Address" value is always equal to "-". I would like to know how Windows can get all the way through a logon, end in failure and not know the peer's IP address.

Also worth noting is the few times that the IP address does get logged the log entry does in fact contains lots of other useful information (like the Process that generated it, the failure reason, transmitted services, etc).

Can someone please tell me why the Security Log doesn't know the IP address of people trying to log in and failing?

  • 1 Might be helpful if you give us an OS version... and/or what level of logging you're doing on Security events, as you may need to increase your logging level to see what you're asking for. –  HopelessN00b Jun 18, 2012 at 18:58
  • Server 2008 R2 Standard. I think the logging level would only affect which events were logged, i.e. whether audit failure gets logged. My problem is the events inconsistently have and don't have the IP address of the client trying to connect. –  kmarks2 Jun 18, 2012 at 19:09

Here is the cause for something like Remote Desktop.

http://cyberarms.net/security-insights/security-lab/remote-desktop-logging-of-ip-address-%28security-event-log-4625%29.aspx

There is no option in Windows to enable or disable the logging of IP address, at least not to my knowledge.

For Remote Desktop I discovered that going into "Remote Desktop Session Host Configuration" and changing the RDP-TCP connection to have the security layer of "RDP Security Layer" instead of "Negotiate" or "SSL (TLS 1.0)" brought back the IP addresses.

Whether you really want to do this is another question for you, "If you select RDP Security Layer, you cannot use Network Level Authentication."

Matthew1471's user avatar

IP addresses not being present in Windows logs isn't all that uncommon, especially if (for example), the failures are coming from a service, like IIS and you only have "basic" level logging for IIS... or SMTP and you have "basic" level logging for SMTP, etc.

Not the way I'd set my logging defaults if Windows was my OS, but Gates never asked for my input. I'd suggest adjusting your logging levels (and expanding the max log file sizes) and seeing if that doesn't resolve the problem. It's not that Windows doesn't know the source IP, but that the logging level is set such that it's not recording that information. (And, for whatever it’s worth, setting the logging level to something useful is one of the first steps I undertake on a new Windows server or server template.)

HopelessN00b's user avatar

Similar to what HopelessN00b said, the most likely reason why you don't see this information is because the audit failure are generated by a service on behalf of the user. So the user isn't authenticating directly (as he or she would when logging into Windows for example), but through some other service like IIS, SQL, etc. You would then have to parse the logs of those services to find out the IP address.

Now, if the authentication is directly through Windows, then you should usually see the IP address, or 127.0.0.1 if it's coming from the local machine.

There is no option in Windows to enable or disable the logging of IP address, at least not to my knowledge. So, there is no real logging "level". You either enable a logging category, or not. The only thing you can configure is whether to log audit failures and/or audit success events (maybe see this article: http://blogs.technet.com/b/askds/archive/2007/10/19/introducing-auditing-changes-in-windows-2008.aspx ).

BTW, there are lots of free products out there which monitor the event logs (e.g. we develop EventSentry ), it's usually much easier to just use that rather than write your own (unless you do it as an exercise of course :-) ).

Hope this helps.

Much probably originated by NTLM inbound traffic. I could not find a way of logging the ip but you can block it, here you can find why is not logged and steps on how to disable inbound NTLM traffic https://serverfault.com/a/729662/200398

You can log from the firewall. If it is a brute force attack from a single IP this will be easily matched. The firewall could be upstream. How you then automate the detection and blocking of the connection is up to you. They will never run out of endpoints.

You might also consider a script that door knocks a hole in your firewall, this is routinely done nowadays on the cloud with NSG (Network Security Group) manipulation in the simplest extremes. Trampolining through jump or bastion servers is also popular.

ip change event log

How can I track changes to network adapter configuration

Ok, so we have a site where most of the users have local admin and they have a small group of users who "know about computers".  The site runs pretty smoothly but we're seeing a bunch of users who are able to function on the wired network but aren't able to function on wireless when they're in the office (works fin elsewhere).  In every case so far, the DNS entries for the wireless connections are set to manual and they have the CloudFlare DNS Server (1.1.1.1) set.  They're able to resolve external hostnames but not internal ones.  They have assured us that no one there would ever make a change like that but we know something is changing it and we know that it's not someone from here.  I'm trying to find an Event that I can search for that indicates that the network adapter configuration was changed.  I'm still Googling it but, thus far, my Google foo has failed me.

I love that idea but there are a few additional things to consider.

- One, the client's core application, per the developer, requires local admin rights for the application to run.  We've reached out, multiple times, to the developer to try to find ways around this (Power User, setting specific filesystem / registry permissions, etc.) to no avail.  Per the software developer, it's a hard no and this is kindof niche software so the client is limited.

- Two, we are an MSP, we work for the client.

What I have found, and it is not always the case, is when I hear that answer from the local developer, I can get around that by giving local users admin access to just the application folder location. I'd try that on a test workstation for giggles.

I know you work for the client, but you also have a responsibility, and I'm sure you already know this, is to let them know the risks involved in that decision to give local users admin rights. In fact, that goes against many cyber insurance policies. There is another software suite, that I can't remember right now, where you can govern admin rights to specific applications, while protecting all your PC locations. Maybe someone can remember for me and chime in.

Jono ​ correct, in *every* case, changing the DNS back to DHCP (so that they get THEIR internal nameserver) resolves the issue.

Denis Kelley  we've actually tried granting full permissions to the install and data directories as well as the registry keys that we are able to see it touching (doing a diff on the registry before and after the install and then using the SysInternals tools to see what else it's touching) but it just doesn't work.  The client has been made aware of the risk but, for the moment, they've deemed it acceptable.  

I'm trying to find an event log entry that says something like "The local network adapter has been changed to have static DNS" (or similar) and am pretty sure I'm going to feel pretty silly when I find it (that it's taken this long AND I had to let you fine folks know that I couldn't find it myself :) ).  Then, I can set a scheduled task to fire on that or use our RMM tools to fire on it and then start narrowing down what's going on (e.g., your DNS changed at 8:07am ET, what were you doing at 8:07am ET?).

"They have assured us that no one there would ever make a change like that" is enough of an answer to report the crime to the FBI. The CFAA makes 'hacking' pretty much any computer in the US a crime. DNS poisoning (or spoofing) is a known attack vector. Does the company understand the risk if the attack being tested on their systems leads to a catastrophic attack on the systems of another company? All of that said, the easy path forward is to log the setting and logged-on user on a regular basis. 'wmic nicconfig get DNSServerSearchOrder' should return the DNS record and 'whoami' will return the username. I would personally run 'time /t' before and after the other two commands. Pipe the output to a file and wait for the next outage.

This idea falls 100% in the "workaround" category. However, given that you cannot revoke local admin and that resetting the NIC to DHCP works every time, I would set up a scheduled task to reset the NIC parameters periodically.

A simple .BAT file (IPCONFIG has the ability to set DHCP on "x" interface) or PowerShell script could be set to run at each machine boot, user logon, specified time interval, etc.

Itemize your bill with a significant charge stating the date and time that you discovered that someone changed the DNS entry and that you corrected it.  Since someone is changing it, it is a personnel problem.  You are being paid to fix technical problems, not personnel problems.

 There is another software suite, that I can't remember right now, where you can govern admin rights to specific applications, while protecting all your PC locations. Maybe someone can remember for me and chime in.

We use BeyondTrust Privilege Management for this. It works beautifully. You can elevate based on dozens of different criteria, including trusted ownership (executable is owned by Trusted Installer, Administrator or Administrators), Publisher name (based on the cryptographic signature of the file) and regular expression matching.

We like the software so much, we also started expanding our use of it so it is now our full-blown application whitelisting/graylisting solution.

Jono  I did some testing on this and, out of the box, this doesn't generate an event in the ​NetworkProfile log.  May be something that we can enable later on but isn't there now.

This is a personnel issue.

Once you have documented it sufficiently, you can tell the powers that be that you are more then happy to keep getting paid to fix this minor issue, but it would be cheaper for them to track down the employee making the changes and correct it.

I've not really researched this but I would think it should be possible for a a PowerSshell script run on login to be able to record the DateTime and what the DNS setting was before changing it - then you could simply check the security logs for the previous account login for that time?

The event logs that you can look for are "NetworkProfile" with Event ID 10000 and 10001, which indicate changes to network profile settings and the source of the change, respectively. 

Another event log is "Microsoft-Windows-NetworkProfile/Operational" with Event ID 10003, indicating a change to the network adapter settings.

Ok, picking the best answer here was kindof tough but ultimately it went to  OscarOneEye ​ .  I don't see a way to have anything like an honorable mention basically everyone here would get one.  I have, I think, a workable solution that we're cobbling together and I plan to post the details here when we have it ready to go but basically the plan is to do the following:

  • I have a powershell script that checks for a "working file" and, if one doesn't exist, creates it with the contents of HKLM:\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\  
  • If one does exist, it creates a temporary file and compares it to the working file using fc.exe
  • If the two are different, it sends an email to our helpdesk with the workstation name and the differences (before and after)
  • We're triggering off of the Event ID 10000, 10001 and 10003 (that trigger was our missing step)

This is admittedly sounds a little cobbled together but the RMM that we use makes it easy for us to create the script to run based on specific triggers (like Event Log entries).  This will give us a specific timestamp (when the event fired), the specific workstation and the specific changes made.  I suspect it'll get a little noisy at first as the users move their computers around (office, home, coffee shop, etc.) but my hope is that we won't have to keep it turned on for long before the offending party either realizes that he / she / they can't hide and quit or we pin down exactly who it is.

Thank you to everyone who pitched in on this!

Thumbs up for a helpful post is all you can do (it does give the person who supplied the post a point ).  SW used to allow helpful posts but they removed that feature

OK, so been a very long time since I've posted on this but it's taken some tinkering to get to where we are.  Ultimately, we don't have a way to find out the who or the why the adapters are being changed but we have been able to find the when , which is helpful.  We're using a combination of a GPO, Scheduled Task and some PowerShell.

- We have setup a GPO to copy a file (the robocopy script, pasted below) and create a scheduled task

- The scheduled task Trigger is the Event ID 4004 in MIcrosoft-Windows-NetworkProfile/Operational (network adapter changed)

- The action is to start a program -> powershell.exe with the arguments -WindowStyle hidden -file c:\ctc\RecordIPConfigChanges.ps1

- The PowerShell script (admittedly quick and dirty / ugly but it's getting us the data that we need) is this:

I believe that the nameservers are actually being changed automatically, likely from some script that was "set and forget" by a prior IT person and we're pursuing it based on that at the moment (the nameservers are being set to a legitimate internal nameserver and 1.1.1.1, so it doesn't seem malicious).  Would welcome any feedback and hope this helps someone else.

Tracking and Analyzing Remote Desktop Connection Logs in Windows

Rdp connection events in windows event viewer, getting remote desktop login history with powershell, outgoing rdp connection logs in windows.

When a user connects to a Remote Desktop-enabled or RDS host, information about these events is stored in the Event Viewer logs ( eventvwr.msc ). Consider the main stages of RDP connection and related events in the Event Viewer, which may be of interest to the administrator

  • Network Connection;
  • Authentication;
  • Session Disconnect/Reconnect;

Network Connection – establishing a network connection to a server from the user’s RDP client. It is the event with the EventID 1149 ( Remote Desktop Services: User authentication succeeded ). If this event is found, it doesn’t mean that user authentication has been successful. This log is located in “Applications and Services Logs -> Microsoft -> Windows -> Terminal-Services-RemoteConnectionManager > Operational”. Enable the log filter for this event (right-click the log -> Filter Current Log -> EventId 1149 ).

windows event log Terminal-Services-RemoteConnectionManager filtering

$RDPAuths = Get-WinEvent -LogName 'Microsoft-Windows-TerminalServices-RemoteConnectionManager/Operational' -FilterXPath '<QueryList><Query Id="0"><Select>*[System[EventID=1149]]</Select></Query></QueryList>' [xml[]]$xml=$RDPAuths|Foreach{$_.ToXml()} $EventData = Foreach ($event in $xml.Event) { New-Object PSObject -Property @{ TimeCreated = (Get-Date ($event.System.TimeCreated.SystemTime) -Format 'yyyy-MM-dd hh:mm:ss K') User = $event.UserData.EventXML.Param1 Domain = $event.UserData.EventXML.Param2 Client = $event.UserData.EventXML.Param3 } } $EventData | FT

powershell script: get rdp conneciton events

Then you will get an event list with the history of all RDP connections to this server. The logs provide a username, a domain (in this case the Network Level Authentication is used; if NLA is disabled , the event description looks differently), and the IP address of the user’s computer.

EventID 1149 - Remote Desktop Services: User authentication succeeded

Authentication shows whether an RDP user has been successfully authenticated on the server or not. The log is located under Windows -> Security. So, you may be interested in the events with the EventID 4624 ( An account was successfully logged on ) or 4625 ( An account failed to log on ).

Please, pay attention to the LogonType value in the event description.

  • LogonType = 10 or 3 — if the Remote Desktop service has been used to create a new session during log on;
  • LogonType = 7 , means that a user has reconnected to the existing RDP session;
  • LogonType = 5 – RDP connection to the server console (in the mstsc.exe /admin mode).

security log: rdp logon event with the username and ip adress of the remote client

In this case, the user name is contained in the event description in the Account Name field, the computer name in the Workstation Name , and the user IP in the Source Network Address .

You can get a list of successful RDP authentication events (EventID 4624) using this PowerShell command:

Get-EventLog security -after (Get-date -hour 0 -minute 0 -second 0) | ?{$_.eventid -eq 4624 -and $_.Message -match 'logon type:\s+(10)\s'} | Out-GridView

list sucess rdp auth event with an EventID 4624

Logon refers to an RDP login to Windows. EventID 21 – this event appears after a user has been successfully authenticated ( Remote Desktop Services: Session logon succeeded ). This events are located in the “Applications and Services Logs -> Microsoft -> Windows -> TerminalServices-LocalSessionManager -> Operational”. As you can see, here you can find the ID of a user RDP session — Session ID .

EventID 21 - Remote Desktop Services: Session logon succeeded

Session Disconnect/Reconnect – session disconnection and reconnection events have different IDs depending on what caused the user disconnection (disconnection due to inactivity set in timeouts for RDP sessions , Disconnect option has been selected by the user in the session, RDP session ended by another user or an administrator, etc.). You can find these events in the Event Viewer under “Applications and Services Logs -> Microsoft -> Windows -> TerminalServices-LocalSessionManager -> Operational”. Let’s consider the RDP Event IDs that might be useful:

  • EventID – 24 ( Remote Desktop Services: Session has been disconnected ) –a user has disconnected from the RDP session;
  • EventID – 25 ( Remote Desktop Services: Session reconnection succeeded ) – a user has reconnected to the existing RDP session on the server;
  • EventID – 39 ( Session <A> has been disconnected by session <B> ) – a user has disconnected from the RDP session by selecting the corresponding menu option (instead of just closing the RDP client window). If the session IDs are different, a user has been disconnected by another user (or administrator);
  • reason code 0 ( No additional information is available ) means that a user has just closed the RDP client window;
  • reason code 5 ( The client’s connection was replaced by another connection ) means that a user has reconnected to the previous RDP session;
  • reason code 11 ( User activity has initiated the disconnect ) a user has clicked the Disconnect button in the start menu.

EventID 4778 in Windows -> Security log (A session was reconnected to a Window Station). A user has reconnected to an RDP session (a user is assigned a new LogonID).

EventID 4779 in “Windows -> Security” log ( A session was disconnected from a Window Station ). A user has been disconnected from an RDP session.

Logoff refers to the end of a user session. It is logged as the event with the EventID 23 ( Remote Desktop Services: Session logoff succeeded ) under “Applications and Services Logs -> Microsoft -> Windows -> TerminalServices-LocalSessionManager -> Operational”.

EventID 23 - Remote Desktop Services: Session logoff succeeded

At the same time the EventID 4634  ( An account was logged off ) appears in the Security log.

EventID 4647 — User-initiated logoff

Here is a short PowerShell script that lists the history of all RDP connections for the current day from the terminal RDS server event logs. The resulting table shows the connection time, the client’s IP address (DNS computername), and the remote user name (if necessary, you can include other LogonTypes in the report).

Get-EventLog -LogName Security -after (Get-date -hour 0 -minute 0 -second 0)| ?{(4624,4778) -contains $_.EventID -and $_.Message -match 'logon type:\s+(10)\s'}| %{ (new-object -Type PSObject -Property @{ TimeGenerated = $_.TimeGenerated ClientIP = $_.Message -replace '(?smi).*Source Network Address:\s+([^\s]+)\s+.*','$1' UserName = $_.Message -replace '(?smi).*\s\sAccount Name:\s+([^\s]+)\s+.*','$1' UserDomain = $_.Message -replace '(?smi).*\s\sAccount Domain:\s+([^\s]+)\s+.*','$1' LogonType = $_.Message -replace '(?smi).*Logon Type:\s+([^\s]+)\s+.*','$1' }) } | sort TimeGenerated -Descending | Select TimeGenerated, ClientIP ` , @{N='Username';E={'{0}\{1}' -f $_.UserDomain,$_.UserName}} ` , @{N='LogType';E={ switch ($_.LogonType) { 2 {'Interactive - local logon'} 3 {'Network connection to shared folder)'} 4 {'Batch'} 5 {'Service'} 7 {'Unlock (after screensaver)'} 8 {'NetworkCleartext'} 9 {'NewCredentials (local impersonation process under existing connection)'} 10 {'RDP'} 11 {'CachedInteractive'} default {"LogType Not Recognised: $($_.LogonType)"} } }}

powershell: list todays rdp logons with an ip and username

You can export RDP connection logs from the Event Viewer to a CSV file (for further analysis in an Excel spreadsheet). You can export the log from the Event Viewer GUI (assuming Event Viewer logs are not cleared) or via the command prompt:

WEVTUtil query-events Security > c:\ps\rdp_security_log.txt

Or with PowerShell:

get-winevent -logname "Microsoft-Windows-TerminalServices-LocalSessionManager/Operational" | Export-Csv c:\ps\rdp_connection_log.txt  -Encoding UTF8

If your users connect to corporate RDS hosts through the Remote Desktop Gateway , you can check the user connection logs in the Microsoft-Windows-TerminalServices-Gateway log by the EventID 302 . For example, the following PowerShell script will display the specified user’s connection history through RD Gateway:

$rdpusername="b.smith" $properties = @( @{n='User';e={$_.Properties[0].Value}}, @{n='Source IP Adress';e={$_.Properties[1].Value}}, @{n='TimeStamp';e={$_.TimeCreated}} @{n='Target RDP host';e={$_.Properties[3].Value}} ) (Get-WinEvent -FilterHashTable @{LogName='Microsoft-Windows-TerminalServices-Gateway/Operational';ID='302'} | Select-Object $properties) -match $rdpusername

rd gateway user connection logs

  • 300 — The user NAME, on client computer DEVICE, met resource authorization policy requirements and was therefore authorized to connect to resource RDPHOST;
  • 302 — The user NAME, on client computer DEVICE, connected to resource RDPHOST;
  • 303 — The user NAME, on client computer DEVICE, disconnected from the following network resource: RDPHOST. Before the user disconnected, the client transferred X bytes and received X bytes. The client session duration was X seconds.

You can display the list of current remote sessions on your RDS host with the command:

qwinsta The command returns the session ID, the USERNAME, and the session state (Active/Disconnect). This command is useful when you need to get the user’s RDP session ID when using shadow Remote Desktop connections .

Qwinsta - list RDP sessions and usernames

You can display the list of the running processes in the specific RDP session (the session ID is specified):

qprocess /id:5

qprocess - get process list for an RDP session

You can also view outgoing RDP connection logs on the client side. They are available in the following event log: Application and Services Logs -> Microsoft -> Windows -> TerminalServices-ClientActiveXCore -> Microsoft-Windows-TerminalServices-RDPClient -> Operational.

For example, EventID 1102 occurs when a user connects to a remote Windows Server RDS host or a Windows 10/11 computer with RDP enabled (desktop Windows editions also support multiple simultaneous RDP connections ).

Microsoft-Windows-TerminalServices-RDPClient connection event in Windows

The following RDP script will display the history of RDP client connections on the current computer:

First at all great article, it helped me already with some analysis.

But i would have a short question about an reason code i receive in the TerminalServices-LocalSessionManager Log, maybe you can help me with it:

“Session 90 has been disconnected, reason code 3489660929”

What is the reason code: 3489660929?

Currently my users are experiencing random disconnects on my RDS 2019 Farm where always this reason code pops up.

Hi. Very good job, it worked awesomely to me.

How can I set the Event Log properties for the Applications and Services Logs.

For windows logs I use “Limit-EventLog -logname …..”, but I can’t figure out how to point to that session.

Thanks for sharing. Very detailed. However, I’m having same issue as Arman. When running PowerShell script on Windows Server 2019, Username results display: “\-” (without quotes).

' src=

If you are getting the “-\-” problem with Domain and username

UserName = $_.Message -replace ‘(?smi).*Account Name:\s+([^\s]+)\s+.*’,’$1′ UserDomain = $_.Message -replace ‘(?smi).*Account Domain:\s+([^\s]+)\s+.*’,’$1′

UserName = $_.Message -replace ‘(?smi).*\s\sAccount Name:\s+([^\s]+)\s+.*’,’$1′ UserDomain = $_.Message -replace ‘(?smi).*\s\sAccount Domain:\s+([^\s]+)\s+.*’,’$1′

Windows 11 servicing stack update - 22621.3073 and 22631.3073

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.

Known issues in this update

Microsoft is not currently aware of any issues with this update.

How to get this update

Before installing this update

Microsoft combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates  and  Servicing Stack Updates (SSU): Frequently Asked Questions . 

Install this update

If you want to remove the LCU

To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages .

Running Windows Update Standalone Installer ( wusa.exe ) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.

File information

For a list of the files that are provided in this update, download the  file information for cumulative update 5034765 . 

For a list of the files that are provided in the servicing stack update, download the  file information for the SSU - versions 22621.3073 and 22631.3073 .
