Remove backup AD Domain controller when dead and not present

[Mark Jerome]

We have Domain with two AD servers. THe one acting as the secondary AD
server failed and we do not wish to repair or restore. Is there any way
(complex or simple) that we can tell the ROOT AD server that the secondary
AD server is not long available or to be used and make it go back to working
as if it is the ONLY AD server?

I've removed backup AD servers before but it was always planned so we
demoted them or returned them to app server status while they were up and
running. We've never just removed it or had one permenantly fail to the
point we had to go back to the root AD and try to manually remove it from
there.

DO you know if this is a simple thing. Is it as easy as going into the
active directory under DOMAIN CONTROLLERS and delete the entry for the
secondary AD server??? Somehow I doubt that it is that easy but thought
I'd ask!

Thanks for any feedback you can provide

Look at NTDSUtil -- someone will likely post the article
reference but you can search the MS Support site and
TechNet for it yourself.

You want to find out how to use NTDSUtil.exe for "Metadata
cleanup"

And don't forget to pick all the references to the dead machine out of DNS

Is there a way to accomplish the same thing, but re-use
the old DC's computer name, so that DNS entries don't
have to be deleted?

Sure. After you do a metadata cleanup, you can reuse the same name. It is
advisalble to clean DNS so that newly installed server reregisters its
records in DNS. This is only to avoid later conflicts.
