Migrate NT4 BDC to W2k Server

By scenturian ·
Hi, I wonder if someone can help? Our NT4 PDC Crashed very hard! We now only have the BDC(NT4) and other servers W2K and 2003. We are using roaming profiles. With the PDC gone we cannot add anything to the domain, and users logging in have to use the locally stored roaming profile. Our solution to our problem is to install a new W2k server with active directory and migrate from the NT4 BDC.
Can someone tell me if this possible? and the steps to take. Our fear is that it isn't and we have to recreate the whole domain from scratch!!!

Promote BDC

by p.j.hutchison In reply to Migrate NT4 BDC to W2k Se ...

On the BDC load up Server Manager and on the Computer menu select 'Promote to Primary Domain Controller'. This will convert the BDC to a PDC.
Then you can rebuild your old PDC as a BDC and when it ready promote that back as a PDC (it will auto convert the other PDC back to BDC).

For the long term, I would seriously consider moving to Windows 2003 to use AD as NT4 is not supported for last 4 years and new h/w will not support NT4 either...

User logins

by scenturian In reply to Promote BDC

Thanks for the reply. There's just another question. With the PDC down should you still be able to view/add/modify users in Administrative tools on the BDC. When i go there i get the message that no domain is available for me edit users and no users are shown. Is that normal? I'm just concerned that the BDC isn't correct and promoting it might somehow cause other problems.

Accessing domain

by p.j.hutchison In reply to User logins

On a BDC you can only view or read members but you cannot change anything until either a PDC is online or a BDC is promoted to a PDC while main PDC is unavailable.
