I managed to call on some support direct from Microsoft in the end on this. Initially, we thought we'd need to dcpromo Server3 & start from scratch. But on checking, it seemed to just be a problem of lingering objects. It took a while to clear them. (We had difficulty resetting the admin...
When I try to run dcpromo on Server3, it says 'Before you can install or remove Active Directory, you must remove Certificate services. For more information about the consquences of removing Certificate Services, see Help And Support'.
On checking, Server3 is the main CA. Server2 says 'Cannot...
DHCP never included any mention of Server1, so nothing to clean up there.
Both remaining DCs have global catolgs since Server1 was removed.
There's no mention in AD Sites & Services of Server1, on Server2 or Server3, so nothing to clean up. I also previously did a metadata cleanup (on...
I just tried replication, and got the following error:
'The following error occurred during the attempt to synchronize naming context <domain> from domain controller Server2 to domain controller Server3: The target principal name is incorrect.
This operation will not continue.'
I then tried...
Ok, both servers have themselves as primary DNS servers & the other as secondary.
Server1 doesn't appear in the DNS records of either Server2 or Server3. However, I checked AD, and lo & behold, Server1 appears in the Domain Controllers list on Server3, but not Server2. (Note: Server2 can...
Hi,
I was wondering if someone could help. We've got bad problems on our domain currently. Until a month or so ago we had 3 DCs:
- Server1 - Primary DC (which was a VMWare Server Host at the time), & DNS Server
- Server2 - Backup DC, DNS Server & Exchange Server
- Server3 - Backup DC, File...
Yes, I did wonder whether it was left long enough, as it can't find the GC. Having said that, I thought I left it for at least a week to switch over, but I could be wrong.
The reason for changing the AD server, was that we needed to convert the physical machine into a virtual one. I tried...
I've had a chance to look at this again. Unfortunately, it didn't fix the problem. I've been looking through various errors in the event log on the DC& one specifically says:
Active Directory was unable to establish a connection with the global catalog server.
(Event ID: 1126)
Active...
Hondy,
Thanks for that. I tried it before, but that was before I cleaned up DNS. It certainly looks better. Hopefully that's the problem sorted, now, thanks.

Hi,
I recently replaced our only DC & DNS server with a completely new server. First of all, I added the new machine to the domain, installed AD onto it, and did a fresh build of DNS, too. I made the new server the Global Catalog, then some time later removed global catalog from the old...
