About Windows 2000 Logon

Hi,
I have one w2k advanced server with active directory and 20 w2k prof. client.i have connected my all clients to domain.But when my clients try to logon on domain it gives me error that “Local Policy not allow to logon interactively”.The i try to logon on those clients as a Local Administrator but again the probs is same.I am also can’t logon locally.I don’t want to install w2k prof again because it’s very difficult.Is there any way to solve this problem.

I would appreciate if someone provide me the solution of this.

With regards.

Anurag.
