WSUS Problem - Konsole weisst auf fehlende Updates hin, aber Clients sind up to date.

Hallo,

ich habe folgendes Problem.
Ich habe einen neuen WSUS Server installiert, eine Gruppenrichtlinie erstellt und alle Maschinen berichten ihren Status und installieren auch einige Updates.
Bei fast allen Maschinen (Server, sowie auch Clients) werden Updates nicht angezeigt.

Hier ist ein Teil des Windows Update Logs.
