  1. Execute PowerShell Code Block on a Remote Computer that call to another ps1 file

    pseudo-code fails for me

    $scriptDeploy = “…. myscript.ps1″

    Invoke-Command -credential $testCred -computer $serverName -Script{

    param([String]$scriptDeploy, [String]$destino) &”$scriptDeploy” -ArgumentoTest1 ‘parametro1’ -RutaDestinoEnMaquinaRemota $destino

    } -ArgumentList $ItemLocation, “$dirRemotoDestino”
