Hello, I installed WSUS on a W2000 server and use GP in the AD. The problem now is that everything seems to be installed allright but i do not see any clients registering at the server. A piece of the windowsupdatelog is attached of one of the clients. The clientdiagnostics did not report an error on the client. Can anyone tell me what goes wrong? Thanks, Peter, Holland.
