I just migrated the old NT4 domain to AD on w2003...
I installed w2003 on the PDC and the AD has been created without any problem...
I just seen that 2 others NT4 server are in the Domain Controlers there are setup as BDC.
I don't think that is really good because the goal now is to set the DC on 2008 server.

Is there any possibility to clean this situation ?
I'm working in parrarel to build another w2003 dc, so I will have 2 servers on w2003...

Thx for you're help
Best regards,

    If you have those BDC online then you can refer to the following MS KB:

    How to remove Windows NT4 BDC (Backup Domain Controller) From Active directory?

    Else you can just delete the NT BDC accounts from the Active Directory (yes just delete the accounts).

    Thx for the link ashutoshsapre...
    What will be the impacts on the server ? (which I will remove from the domain)
    I noticed that it will prevent the BDC (Backup Domain Controller) functions and will drop the option to use network resources from the domain.
    But in fact what does that means?
    I have share folders on the NT4 they still be reachable ?
    How can I login on this server after the deletion ?

    Best regards,

    Accepted Solution

    Windows 2K8 and NT4 cannot co-exist.
    You'll need to decide what's more important to you.
    I'd guess that since it's only a fileserver, you can easily(cost dependant), move these folders to other servers.

    The other instructions given should work for removing those BDC's

    So the best way is to move the existing on another server or migrate NT4 to windows 2000 or 2003 if possible ?
