Um dieses Problem zu lösen, habe ich ein PowerShell-Skript geschrieben. Dazu habe ich mich von Inhalten von Jason Scheffelmaer inspirieren lassen. Um das Skript nutzen zu können, benötigt man die SCCM.psm1 von Michael Niehaus.

Das Skript wird ohne Parameter aufgerufen und fragt alle notwendigen Werte bei der Abarbeitung ab. Wichtig ist, dass die x86-Variante der PowerShell verwendet wird. Im Skript selber muss noch der Pfad zur SCCM.psm1 angepasst werden.

# Get-SCCMMissingTSPackages.ps1

# Author: Haiko Hertes
# Parts of the Script are taken from CheckTSPrompt.ps1 from Jason Scheffelmaer
# Needs sccm.psm1 from Michael Niehaus, tested with Version 1.5
