Back in July we had a problem where ‘Active Directory Domain Services was unable to establish a connection with the global catalog’. That was thankfully resolved by a very helpful expert on Expert’s Exchange.
Link to previous problem.
But we are still having problems with our XP clients, where by when the clients first boot up the client will say ‘preparing network connections’, this dialog may sit there from anywhere from 20secs to 4 minutes. Then if you try and logon to the domain another dialog will come up and say ‘domain unavailable’. But if you wait a few minutes you can log in, but we get these errors from the even viewer:
Eventid: 1058 - windows cannot access the file gpt.ini for GPO
Eventid: 1053 – windows could not determine the user or the computer name (the specified domain either does not exist or could not be contacted).
Eventid: 15 – Automatic enrolment for local system failed to contact the active directory. The specified domain does not exist or could not be contacted.
Eventid: 1054 – windows cannot obtain the domain controller name for your computer network.
Eventid: 1054 – Windows cannot query for the list of group policy objects.
When a user does login after these errors, we can run ‘gpupdate /force’ and that does seem to resolve the problem for the current user, but when a new user logs in same issues.

Any help on this would be a massive help.
