How can I promote a Windows 2000 server to PDC in a mixed
envoirment (Windows 2000 - Windows NT 4.0) if the PDC
(NT4.0)fails and I promoted a BDC NT 4.0 to PDC in order
to maintain the operation. Now I need to install a new
PDC in Windows 2000 server.
Technically you cannot do what you ask -- it's either a technical or a
terminology issue depending on your point of view.
No Win2000 can be a BDC -- no NT domain controller cannot be
installed UNLESS it is installed as a BDC initially.
Only the NT PDC can upgrade a domain to Win2000+. Upgrading
any other machine ends up with either a "new domain" or a non-DC.
[Technically no Win2000 DC is a "pdc" either, just a DC but that's
not real important to the issue.]
The way to accomplish what you wish follows, and it will convert the
domain to a Win2000 domain in the process:
1) Add an NT 4 BDC to the domain
2) Promote this BDC to PDC
3) Upgrade this PDC to Win2000...voila: a Win2000 Domain
Alternative (really the same):
1) Upgrade existing PDC to Win2000
2) Install a Win2000 server
3) DCPromo the new server to be an additional DC in the domain***
*** Unlike NT domain controllers, Win2000+ DCs can easily become servers
again, and easily be promoted to become a DC.
