Clients not showing up on WSUS3

[shahid129]

I have WSUS 3 sp1 running on my Server, all the clients are supposed to get the updates using GP.
I have checked everything and i have run a client diagnostic but it seems that the clients just do not show up in WSUS 3. This has been doing my head in a good few days.
I have added the results of the Client Diagnostic that i have run on one of the PC's
