    Hi @Bruce Taylor ,

    maybe this helps to get started:

    add $LASTEXITCODE at the end of check_cluster_node.ps1

    than modify the last line of the script you posted above: 

    $result = Invoke-Command -ComputerName $IPaddress -Authentication Negotiate -Credential $creds -FilePath \tmp\check_cluster_node.ps1 -ArgumentList $Clustername  
$result

    The variable $result should contain the output of $LASTEXITCODE.

    Hi @Bruce Taylor ,

    could you please try this: 

    $Clustername = "NameOfCluster"  
$ServerName = "NameofServer"  
$creds=import-clixml -Path /tmp/tent.xml  
$S = New-PSSession -ComputerName $ServerName -Credential  $cred  
$result = Invoke-Command -Session $S -FilePath \tmp\check_cluster_node.ps1 -ArgumentList $Clustername

    This is what you wanted correct
    $Clustername = UHSISMONCPRB
    $ServerName = 172.20.231.69
    $S = New-PSSession -ComputerName $ServerName
    $creds=import-clixml -Path /tmp/tent.xml
    $result = Invoke-Command -Session $S $IPaddress -Authentication Negotiate -Credential $creds -FilePath \tmp\check_cluster_node.ps1 -ArgumentList $Clustername
    $result

    Can we see the script that runs on the remote computer?

    The Invoke-Command will return all data sent to the Success stream during the execution of the script on the remote machine. "Echo" is an alias for the "Write-Output" cmdlet so that data should have been returned.

    I ran a simple test:
    $creds=get-credential
    $whathappened = Invoke-Command -ComputerName srv02 -Authentication Negotiate -Credential $creds -FilePath c:\junk\untitled-1.ps1

    of this script:
    "Hello, there!"
    $return = 0
    $return

    and received this as the result on the local machine:
    PS C:\Users\richm> $whathappened

    Hello, there!
