I am not able to get my computers to populate the pc's list in the Update Services. There is a domain that I have with 300 machines and they are getting their update information via Group Policy and WSUS installed or setup on a Windows SErver 2003 box. All of these machines are not cloned and they all have different SID's. I have checked that the computer's are getting the policy correctly by browsing to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate and seeing that the server name is in the list for the 2 entries: WUServer and WUStatusServer, in the "http://servername" format. I am able to ping/rdp the server from any machine in the network. Can anyone help me out.
