The most you can expect with what you have done so far is to add the Win 2k
to your NT 4.0 domain as a member server. Promoting it to a DC will result
in creating a new domain.
To move to Win 2k from NT 4.0 will require you to set up two separate
domains on the same wire, create a trust between the two domains and use
ADMT to migrate users from the NT 4.0 domain to the Win 2k domain
See:

OR
You can upgrade NT 4.0 to Win 2k by upgrading the PDC first. The PDC is the
ONLY DC on a NT 4.0 domain that holds a writeable copy of the SAM. Upgrading
the NT 4.0 PDC to Win 2k will carry the NT 4.0 SAM into the new Win 2k
domain.
Promoting *any*other*DC*member server* etc.. will result in a new domain
different from your NT 4.0 domain because the SAM is different.

You need to plan this better either upgrade or migrate. The path you are
taking will lead to a new domain where all users info will have to be
manually entered.
I would suggest removing Win 2k from the new server and installing NT 4.0 on
it as a BDC while connected to your existing domain, promote to PDC (which
demotes your existing PDC to BDC) then upgrade this machine to Win 2k and
AD.
