Gelöst - Client bekommen keine Updates von WSUS

Hallo Community,

ich habe ein Problem mit meinem WSUS. Meine Clients bekommen keine Updates und ich weis leider nicht mehr was ich machen soll/kann.

Die Clients sind W7 x64, W2k8 & W2k8R2. Der SUS läuft auch auf einem W2k8R2 Server.
Version des Update Service ist: 3.2.7600.226.

Folgende URL´s sind erreichbar:
http://computername/selfupdate/wuident.cab
http://IP/selfupdate/wuident.cab

Auf einem Client habe ich folgendes Log(C:\Windows\WindowsUpdate.log):
