I've installed MS WSUS (SP 2 or 3) on a Windows Server 2008 32-bit server.
I've done some basic configuration, and the only computer it lists under All Computers or Unassigned Computers is our domain controller (seperate to the server WSUS is installed on).
Under Update Services > Options > Computers, "Use the Update Services console" is selected to specify how computers are assigned to groups.
The DC's name is the fully qualified host.domain.name, etc, and I can ping a PC using it's own full host name from the WSUS server.
I've clicked Refresh, and no other PCs appear.
The WSUS service is currently sychronising with the remote MS Update server, and I am unable to change how computers are assigned to groups while it is synching. Is the service synchronisation preventing new computers from being added/detected, perhaps to conserve bandwidth/resources?
How else do I have them detected under Unassigned Computers?
