I have a Windows 2003 server that is running as a member server in an AD domain. This server is currently the WSUS server for our environment and through a GP, all of the clients check into this server for their updates. The clients are running XP Pro and are in the same AD domain.
I noticed that the Office 2003 SP2 and Office 2003 SP3 fail to install on the clients although the clients can get every other XP update. I haven't seen any errors in the event viewer on the WSUS server or on the hand full of clients.
