Hello

Thank you for your question and reaching out. I can understand you are having query\issues related to Powershell.

1. Please verify that "Enable Distributed COM on this computer" is Enabled.
2. Please try to use Invoke-Command to run command from Remote server.

Invoke-Command -ComputerName Server01 -Credential Domain01\User01 -ScriptBlock

{

your command

}

3. Disable any Antivirus program or Windows firewall you may have for temporary purpose.

Did you ever get an answer to this? I'm running into the same issue.

Graveyarding this one.

Its a security blocker on the file, because cab files are potentially dangerous. You can right click it and even before you get Properties, it will ask to continue because "Internet security settings blocked this file"

You need to either disable this (Not recommended) or make sure you run your Powershell as Administrator, which should bypass this block also.
