Windows Domain
 

Has anyone ever made a Windows 2003 server part of a 2000 domain? By the way we are using Exchage 2000.

Yes I have
 

I have made a Win2K3 server part of a Win2K domain (I had a customer do this). You can even make it part of an NT4 domain if you wish (I also had a customer do this).

Are you looking to run Exchange 2003 on it? If so, make sure your domain controllers are running SP4 :).

Thanks,

Mitch
