Hello Everyone,
I am trying to get install status from a remote computer into a multilline textbox.
It is not working on some computers and It is giving an error on others. At the bottom of this posting you will see the error.

try {
	$txtStatus.Text = Invoke-Command -ComputerName $listbox1.SelectedItem -ErrorAction Stop -scriptblock { Get-WUInstallerStatus }
		$txterrbox.Text = $_.ErrorDetails

Error detail :
[G4C6QH2] Connecting to remote server G4C6QH2 failed with the following error message : The WinRM client cannot process the request because the server name cannot be resolved. For more information, see the about_Remote_Troubleshooting Help topic.

I confirmed winrm is setup correctly. and I am running the script as admin rights. I also used below line.
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Confirm:$False -Force

thanks in advance.

I’d suspect you have a problem with your DNS. We cannot help you troubleshooting your network issues but the first thing I’d try would be to ping the remote system. :wink:
