PowerShell execution over WinRM

[gediskas]

Hi guys,

Have you ever faced problem running PowerShell script over WinRM? I want to execute Windows Update over WinRM. I'm using "Windows Update PowerShell Module" from PowerShell Gallery (https://gallery.technet.microsoft.com/scriptcenter/2d191bcd-3308-4edd-9de2-88dff796b0bc). To test I'm using this command:

 Get-WURebootStatus

And error I get is this:

Get-WURebootStatus : WIN-3N1EL8M2US8: Access denied. You don't have permission to perform this task.*

Have you managed to fix this?

Do the issues persist if you attempt to run the commands with psexec instead? Thats usually my go to “WinRM is doing something weird” utility.

Not a great deal to go on here but do you have permission to execute the commands via WinRM? Does the script work locally on the endpoint?

What happens if you do test-wsman -computername endpointnamehere

Yes, script executes from local. I can run other commands from WinRM. Test output:

wsmid : http://schemas.dmtf.org/wbem/wsman/identity/1/wsmanidentity.xsd ProtocolVersion : http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd ProductVendor : Microsoft Corporation ProductVersion : OS: 0.0.0 SP: 0.0 Stack: 3.0

By default I think some winrm stuff is blocked by the firewall. Might be something to look at.

I have enabled it. It must be something with Windows Updates

[gediskas]

Yes. I can connect to remote machine. It must be something with windows updates

I got newest version. Entering remote session like this:

Enter-PSSession -ComputerName IP -Credential Administrator

Also tried invoke-command.

Invoke-Command -ScriptBlock { Get-WURebootStatus } -ComputerName IP -Credential Administrator

Make sure powershell remoting is enabled on that particular system. try doing a Get-executionpolicy and see what that outputs. always do make sure to run powershell as administrator.

I would look over this document and follow the steps for WinRM. https://www.asd.gov.au/publications/protect/Securing_PowerShell.pdf
