Confusing Powershell behavior

Question

Am a bit confused w/ remote executing a powershell command. I have a test server (Win 2k8-R2-SP1) called ServerA, which has powershell remoting enabled correctly. From my dev machine (Win 2k8-R2-SP1), am able to remote execure powershell commands correctly. But, when I try to execute the same command from a different server called ServerB (Win 2k8-R2), I get the following error

[ServerA] Connecting to remote server failed with the following error message : The client cannot connect to the destination 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

All three machines are in the same domain. My confusion is that from my dev machine, I am perfectly able to connect to ServerA and execute the command.

Will the fact that ServerB does not have SP1, make a difference? Please advise. I am using the same domain account which has admin rights on all 3 servers.

And the command that I am trying is Invoke-Command -ComputerName ServerA -ScriptBlock {Get-UICulture}.

Please help.

Thanks

Answer 1

Run winrm quickconfig or Enable-PSRemoting -force from ServerB.

Verify service is running with get-service winrm

Also, run this from your local dev box:

Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force
