Joining AD Domain

By Megtek ·
Hey there.

I have an existing NT PDC. I installed a Windows 2000 Advanced Server to my network, and configured AD. Somewhere, the NT server and the 2000 server did not get put into the same domain. I renamed the Domain for the NT server thinking I could re-add it to the current domain, and it will not let me.

Help.

what mode is the W2K server running? W2K has to run in mixed mode for NT servers to be a part of the same domain. Which server is now the PDC? The NT or W2K w/AD?

After installing Windows 2000 Advanced server you need to run DC promo to make that server the first server (domain controller) in the Active Directory. Also ensure that you have configured your DNS correctly.

Joining AD Domain

An NT 4 PDC cannot be part of an AD domain - the Win2K AD domain controller has to be configured as the first domain controller in the forest and domain, and then the NT 4 system can be a BDC in that domain. If the domain names are the same, you can try to demote the PDC to a BDC (off-line) and then reconnect it to the domain and it may work. However, if the domain names are different, you will have to reinstall NT on the old PDC completely, because even if you change the name, the SIDs will be different and the PDC will not accept a new SID from the Win2K computer, even though the domain names are now the same. That said, if you are in that situation, you'd be better off going this way: demote the PDC to a BDC (in its old domain); upgrade it to Win2K (configured as a member server at that point) and join the new domain; and then run dcpromo to make it a Win2K DC in the new AD domain. If you need more details or clarification, feel free to email me directly. Hope this helps!

If this is a corporate domain structure, you are a bull in a china shop. There is a reason why there are volumes of books written on this subject, .... because is is a delicate process!

Clearly you don't know enough about AD or the NT domain structure and associated methods to be dabling around. You should stop where you are and either get professional help or training, before you cause a company-wide disaster.

BTW, you can't just rename entire domain structures w/o significant consequences, because the name is just a user friendly association, the real domain name is a long, complex number value and it can only be changed by re-installing the OS on a PDC.You need to go through a Domain upgrade process as defined in the MS W2K Resource Kit.

I agree, but correct just the same.
