I agree - here's why.
When you delete an object from Active Directory, it leaves a tombstone which
is replicated to other DCs telling them to delete their copy of the object.
By default, tombstones exist for 30 days (I think - however, you can change
this). If the server is out of the loop for longer than the tombstones
existence, then it will continue to show an object that has been deleted
from all other servers. I believe that there is a complicated hack to
remove such orphaned objects, but it's far simpler to demote and then
promote a DC to give it a clean copy of AD.

I vote for demoting it. Excellent recommendation.

As long as you don't change the other Domain Controllers (ie re-install
W2K), I don't see any reason why the machine won't boot up and replicate
the new changes.
Something that may help tremendously is to demote the off-line machine
to a member server, then promote it when it is back online. This will
effectively force a full copy of the AD onto the machine. Otherwise,
the machine will probably have a lot of traffic as it copies all the
changes that have happened over the weeks.
Anyone else want to comment?

Subject: [ActiveDir] Offline Domain Controller
I currently have a native mode domain set up within one active directory
site. There are 3 domain controllers in this site. Because of some
network issues, I had to take one of the domain controllers off of the
network. This domain controller does not have any roles associated with
it (ie.. pdc emulator, schema master, etc). My question is, how long
can I have that domain controller off of the network? It may be a few
weeks before I can get it back online. Will it just come back up and
replicate or is there a time limit involved where the domain will no
longer treat that domain controller as a valid controller in the domain?
Thanks in advance.
