Trust relationship issue between Win 2K3 member server and NT4 domain

[ChrisD.]

I'm hoping someone here can help as I'm all out of ideas.

Freshly built Win 2K3 server, all ready including the correct network settings. All that remains is adding it to the existing NT4 domain.

Anyway I add it to the domain, use my NT4 credentials to verify the add, reboot and try and log onto the domain and I can't however I can still log on locally. If I go onto the PDC I can see the server appearing in server manager but it's greyed out and if I double click on it I get an error message saying there's a trust relationship issue between the computer and the domain.

Using the freshly built server I can map to existing 2K3 servers on the domain but if I try it the other way round I get the trust message again.

Any idea's please? It's doing my bloody nut in.

I take it you haven't already dcpromo'd this 2K3 box, as that would be your first issue.

When you join the 2K3 box to the existing domain, can you see it listed on the PDC in the computers container of AD Users and Computers?

If you can, you can right click on it and choose Delegation.

Alterntaively, you need to look at AD Domains and Trusts but this is normally for cross domain trusts.

Is your PDC in mixed mode? Right click on the domain in AD U&C and choose properties and see what it says for Domian and Forest functional levels.

EDIT: I see you already have some 2003 boxes. so mixed mode / native mode shouldn't be the issue.

The PDC is an NT server, so I don't have those options. I can see the server within server manager on the NT box.

We think we've found the issue, I will update tomorrow.

I should have said, the domain is entirely NT.
