Run powershell command or script for discovery pattern extension

[Quan Nguyen]

I'm attempting to run a powershell command to pull attributes.  I created a extension to the Windows OS discovery pattern.
But, I'm not getting any results.  Does anyone have any clear examples of getting this to work (powershell scripts or commands).

I followed instructions here, but it doesn't work.

Computer UUID

    # REQUIRED VARIABLES
    $error.clear()

    Try {
        # DO WORK HERE
        $CompUUID = get-wmiobject Win32_ComputerSystemProduct -computername '.' | Select-Object -ExpandProperty UUID

    } Catch {
        $_
    }

-----------------------------
Domain Machine SID
-----------------------------
    # REQUIRED VARIABLES
    $error.clear()

    Try {
        # DO WORK HERE
        #use the computername followed by a $ sign to get the SID the domain gave the machine (should work offline as the machine keeps a copy)
        [string]$domainCompName = "$($env:COMPUTERNAME)$"
        
        $ID = New-Object System.Security.Principal.NTAccount($domainCompName)
        $IDTranslated = $ID.Translate([System.Security.Principal.SecurityIdentifier])
		$DomainMachineSID = $IDTranslated.Value

    } Catch {
        $_
    }

Is Above Code Snippet is working using Power shell Prompt from Mid Server?

Chck Powershell Access and execution  on Target Host Server/IP

$target = "<target_ip>"

$userName = "<user_name>"

$userPassword = "<user_password>"

$securePasswd = ConvertTo-SecureString $userPassword -AsPlainText –Force

$cred = New-Object System.Management.Automation.PSCredential ($userName, $securePasswd)

$session = New-PSSession -ComputerName $target -Credential $cred -ConfigurationName Microsoft.PowerShell32

Enter-PSSession $session

Invoke-Command -Session $session -FilePath c:\file_path\file_Name.ps1

Exit-PSSession

 Store your Script in given Path and file on mid server ..This is just a raw test.

Regards
