Summary

PowerShell remoting allows for the execution of scripts located on a local server to be executed remotely

There are several ways to invoke commands and run scripts remotely with PowerShell

The command ‘Enter-PSSession‘ may not work when used in an Argent Guardian Ultra – PowerShell Rule

Technical Background

Several PowerShell commands are meant for interactive mode execution (e.g. Keyboard Input) and may not work when executed from the Argent Guardian Ultra PowerShell execution context

Argent is still investigating this issue and may support this in future

Resolution

Use the command ‘New-PSSession‘ together with ‘Invoke-Command‘ as an alternative to ‘Enter-PSSession‘

Example PowerShell Script Remote Execution Rule:

$session = New-PSSession -ComputerName $PSPlayer.TargetServer



$remoteHostname = Invoke-Command -Session $session -ScriptBlock { hostname }



$remoteIpconfig = Invoke-Command -Session $session -ScriptBlock { ipconfig }



$remoteHostname



$remoteIpconfig



Remove-PSSession -Session $session
