Remove DC from AD manually

Posted on 2009-12-27

I have a test environment running some virtual servers. In my domain,, there were 3 DC's - DC1, DC2, DC3. All FSMO roles are held on DC1.

DC2 and DC3 are shut down and I don't want to start them again (simulate a HDD failure on them).

I would like to install Exchange 2007 on DC1, however it fails with the following error:

The FSMO role ownership could not be verified because its directory partition has not replicated successfully with atleast one replication partner.
The extended server error is:
000021A2: SvcErr: DSID-030A0AF2, problem 5001 (BUSY), data 0

So I assume that because DC1 cannot replicate to DC2/DC3, Exchange 2007 won't install.

How can I manually uninstall DC2 and DC3 from AD? I assume I need to run ADSI, but what exactly do I delete?

    Easiest thing to do is run DCPROMO /FORCEREMOVAL on both DC2 & DC3 then do a METADATA cleanup on DC1 to remove any records for DC2 & DC3 as  per:

    You will also need to check the FSMO role holders as per:

    If DC1 doesn't hold some of the 5 FSMO roles you will need to seize them as per:

    If you have to seize any roles then the server that you seize them from must be formatted before being rejoined to the domain.
