NT4.0 PDC and W2k AD on same domain

[Guest]

It looks lie some one at work Dcpromo’ed a NT BDC on a current NT 4.0 domain. What will be the repercussions of having AD and a NT PDC on the same domain? I believe the distant admin, just turned off the machine without Demoting the new AD DC. Suggestions? Comments?

This is not a supported scenario. The NT4.0 PDC must be upgraded.
Windows2000 Domain Controllers can't act as BDCs or Domain Controller to an
NT4.0 PDC.

what if the AD dc could come back online? Could we then dedemote it? But, will it leave bits and pieces of promition in the current DNS and the other NT4.0 BDC's

What a freaking mess.....

Thanks Tod

Sorry I don't understand this question, come back online? there can never be
an WIN2K or WIN2K3 Domain Controller in an NT4.0,

If you not want to do an inplace upgrade if the NT4.0 PDC. You can build a
new domain and then migrate over existing object from the NT4.0 domain with
the tool ADMT.

Our planed migration to 2K3 is about 3 months away, but a remote admin. lost his mined and installed 2K AD. The question I am trying to get to: Is there any way to revert back to a pure NT Domain (by demoting the 2K DC and rebuilding DNS(if need be), or are we, in technical terms, hosed

Okay I understand the situation yes you can demote the Windows2000 DC if you
are in mixed mode (it's by default) then open Server Manager on the Windows
NT 4.0 BDC and promote this computer to a primary domain controller (PDC).
If a message appears stating that it cannot contact the PDC and asks if you
want to continue, click Yes, and then complete the promotion. When this is
complete and the server restarts, verify in Server Manager that the computer
it is now described as the PDC.

What Chriss says. But the other option is to keep the 2000 DC
*offline* and rebuild it as an NT4 BDC in the NT Domain. But this
would not preserve the information on it.
