Server Wsus su w2k8 e client Win 7

[fabiopig]

Salve a tutti,
ho un w2k8 con wsus 3.0 SP2 installato, il server si sincronizza perfettamente e si scarica tutti gli aggiornamenti che gli ho configurato, tutti i client risultano con il triangolino giallo in quanto alcuni aggiornamenti risultano approvati ma non installati.
Sui client (Windows 7) ho provato ad riavviare il servizio:

net stop wuauserv
net start wuauserv
wuauclt /resetauthorization
wuauclt /detectnow

quando vado a controllare i log dl client ho quanto segue:

Secondo voi quale può essere la causa di questo malfunzionamento?
Qualcuno può darmi qualche dritta per risolvere il problema?

Grazie
