I have an nt4.0 domain with one server (pdc) I have a new server with win2000 still in the box, I would like to make the new server the dc for the domain and keep the nt sever a bdc. can i do this and will the w2k server replicate usernames/passwords to the nt server. If so what would be the process to do this upgrade

I believe the Microsoft recommended way to do this is as follows:

Install NT on the new server, as a BDC.
Promote it to PDC
Upgrade it to 2K

Your old PDC will now be a BDC in a mixed-mode W2K domain.

The following rules must e followed to successfully migrate an NT4 domain to Win2K and Active Directory:

1. An NT4 PDC CANNOT exist in a Win2K Active Directory (AD) domain (NT4 BDCs can exist in a Win2K mixed-mode domain).
2. Win2K Domain Controllers (DCs) CANNOT exist in an NT4 domain.
3. To migrate a domain from NT4 to Win2K, Win2K (and AD) MUST be installed on the NT4 PDC (will not work on a BDC).

Based on these rules, and assuming you want your new server to become your "master" DC (there is no more PDC/BDC relationship in Win2K; the first DC installed does have some additional roles assigned to it), the process mentioned in the first answer is the quickest way to go.
