How to remove physically disconnected DC from Active Directory


G

Guest

Dear .......

I had 2 domain controllers in my Active directory. The 2nd DC was physically
disconnected without removing it from AD.

Now, 1st DC is still running having AD.

How I can remove the 2nd DC (physically disconnected and not available) from
Active Directory.

Thanks,

On the no-longer-on-the-network DC run the following command:

dcpromo /forceremoval


Then, on the other DC, follow these instructions to clean up the bit's and
pieces left behind by the long-gone DC:
-- http://support.microsoft.com/?id=216498


There are several points to take into consideration when doing a
/forceremoval:

-- Not all services are set back to manual, e.g. Ntfrs
-- The SYSVOL and NETLOGON shares still exist and will need to be removed.
-- The Dir Svc, DNS, and Ntfrs event logs are never going to leave (if
someone knows how to get rid of these, please do tell <g>)
-- There'll still be references to the originally hosted domain in DNS if
you re-setup DNS. You'll have to search the registry for the old domain
name and remove these entries.

There's probably more, but I can't think of them off the top of my head
right now.

Hope this helps,

Well yes I did have a 'to-the-point' suggestion, actually...

That's saying run the metadata cleanup to remove all traces of the now-dead
DC from your AD. Which, if I'm not mistaken, is what you were asking; is it
not?? <grin>


I only mentioned the /forceremoval switch bit because I read that the DC was
disconnected - not that it had died.

If the DC has run out of RIDs then it is not able to contact the RID master
OM role holder -which, was probably the dead DC.

You'll need to seize the OM roles from the dead DC to the new one. You do
this using ntdsutil. Here's and MS KB that walks you through this:

You need to *seize* in this instance; not transfer.
