I have been handed the network from hell. One Windows 2003 server and maybe 15 XP SP2 workstations. NETDIAG and DCDIAG come up clean on the server. The GPO does not update any of the workstations. When I drop to a command prompt and run gpupdate on a workstation here is what shows up in the event log.
Event ID: 1053 Windows cannot determine the user or computer name. (Access is denied. ). Group Policy processing aborted.
Drives are mapping OK. Everything seems to be working but the GPO updates. I did notice while looking at the DNS on the server that only maybe 2-4 workstaions are registering with the DNS.
Since the GPO isn't updateing to any of the workstations I would have to assume that something is incorrect with the server but as I said NETDIAG and DCDIAG come up clean. Any ideas?
