I have just installed WSUS 3.0 on our Windows 2003 box, and the install has gone well, the server is available functioning and syncing quite happily with Microsoft Update.
I have followed the deployment instructions by linking a new GPO object to the domain and have checked that the clients are receiving the correct GPO when logging on. If I check the local registry it tells me that the clients are pointed to our WSUS server to receive updates.
However I cannot see any client computers in the WSUS computer group on the server, so it reports its got nothing to push the updates to.
Thanks in advance
