We have a pretty smal network. We run a Windows 2003 Server SP2. We recently replaced 3 XP computers on our network with Windows 7 Professional. Once these computers joined the domain, the Windows update feature is disabled. The Windows update has line that reads You receive updates: Managed by system administrator. I do not have Group Policies in my domain. We have never configured any at all in our small domain.
At the present, the only way to get updates is to join a workgroup and then I can get updates. I am at a loss as what to do. I can't find anything on our server restricting access.
