How to run powershell scriptblock as domain user? - windows

Question

I have a script block that I'm trying to make it run as a different domain user.
$Username = 'domain\test'
$Password = '1234'
$pass = ConvertTo-SecureString -AsPlainText $Password -Force
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList $UserName,$pass
Invoke-Command -ScriptBlock{
write-host "hello"
} -Credential $cred -ComputerName $env:COMPUTERNAME
When I run it I got the following error:
[test-pc] Connecting to remote server test-pc 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 se
rvice: "winrm quickconfig". For more information, see the about_Remote_Troubleshooting Help topic.
Why the script is trying to authenticate locally and not against the DC ?
Thanks

If you don't actually want to run the script remotely, you can use Start-Process to run Powershell as another user, which will then execute your command/script as that user.
(See powershell command line help for full syntax options and examples)
# Using Get-Credential to illustrate, substitute with your own credential code
$cred = Get-Credential
# Run Command:
Start-Process -FilePath Powershell -Credential $cred -ArgumentList '-Command', 'Write-Host "Hello"'
# Run Script:
Start-Process -FilePath Powershell -Credential $cred -ArgumentList '-File', 'C:\folder\script.ps1'
