Removing domain controller
 

One domain with three domain controllers - A, B, and D. A has gone. The remaining two were still behaving as though A was there - trying to replicate with it. I've used ntdsutil to remove the A server and I have now been able to delete it from Sites and Services, but I can't delete the server from the Domain Controllers OU. Do you think a reboot would help? The B and D servers are now replicating, which is good.

I've always used Dcpromo, which doesn't require a reboot after you've removed the DC from the OU.

dcpromo would be what I would have run on the A server before it vanished. It's a customer at work - got to sort it out tomorrow. Various things wrong, not least of which is the lost A server. It still had the global catalogue along with the D server. Bit of a mess. D has the FSMO roles. I'm hoping that after telling the remaining domain controllers that A has gone, a reboot will either make the A server vanish from the DC OU or at least let me delete it.

I sorted it with the support tools - adsiedit.msc Just went through and deleted references to the A server. Seems fine now.
