<# WaitForAD

Beispiel für die Variablen:
    
    [string]$VMName = "SERVER-VM01"
    [System.Management.Automation.PSCredential] $tempCred = new-object -typename System.Management.Automation.PSCredential ("Domain\Admin", (ConvertTo-SecureString P@ssw0rd! -AsPlainText -Force))

Oder ggfs. die Variablen abfragen:

    $VMName = Read-Host "Bitte den Namen des virtuellen Computers eingeben"
    $tempCred = Get-Credential
