Problem using Invoke-Command with Windows 7 client

While testing some code that used PowerShells Invoke-Command to send code to both Windows Server 2008 R2 and Windows 7, I discovered an inconsistency in the way Windows Remoting is applied to both platforms. The servers worked fine. Even though I disabled to firewall for testing, I received this error when sending commands to the Windows 7 client:

[ClientName] Connecting to remote server failed with the following error message : The client cannot connect to the destingatoin specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service” winrm quickconfig”. For more information, see the about_Remote_Troubleshooting Help topic.

+ CategoryInfo : OpenError: (:) [], PSRemotingTransportException

+ FullyQualifiedErrorId : PSSessionStateBroken

The fix that I came up with was to deploy and Group Policy that allowed remoting and scope it to the client.

1. Open Group Policy Management console
2. Select the domain, and right-click the Default Domain Policy to edit it
3. Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Remote Management > WinRM Service
4. Allow automatic configuration of listeners, put * in the IPv4 and IPv6 filter text boxes
5. Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Remote Shell
6. Allow Remote Shell Access, Enabled
7. Save everything. Run Gpupdate on all servers that are currently running.

Adding a Comment to a GPO with PowerShell

As I'm writing this article, I'm also writing a customization for a PowerShell course I'm teaching next week in Phoenix. This customization deals with Group Policy and PowerShell. For those of you who attend my classes may already know this, but I sit their and try to ask the questions to myself that others may ask as I present the material. I finished up my customization a few hours ago and then I realized that I did not add in how to put a comment on a GPO. This is a feature that many Group Policy Administrators may not be aware of. This past summer I attended a presentation at TechEd on Group Policy. One organization in the crowd had over 5,000 Group Policies. In an environment like that, the comment section can be priceless. I always like to write in the comment section why I created the policy so I know its purpose next week after I've completed 50 other tasks and can't remember what I did 5 minutes ago. In the Group Policy module for PowerShell V3, th

Return duplicate values from a collection with PowerShell

If you have a collection of objects and you want to remove any duplicate items, it is fairly simple. # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2 # Remove the duplicate values. $Set1 | Select-Object -Unique 1 2 3 4 5 6 7 What if you want only the duplicate values and nothing else? # Create a collection with duplicate values $Set1 = 1 , 1 , 2 , 2 , 3 , 4 , 5 , 6 , 7 , 1 , 2 #Create a second collection with duplicate values removed. $Set2 = $Set1 | Select-Object -Unique # Return only the duplicate values. ( Compare-Object -ReferenceObject $Set2 -DifferenceObject $Set1 ) . InputObject | Select-Object – Unique 1 2 This works with objects as well as numbers. The first command creates a collection with 2 duplicates of both 1 and 2. The second command creates another collection with the duplicates filtered out. The Compare-Object cmdlet will first find items that are diffe
