Removing a non existent domain controller from a domain
Hi,
Have a 2008 Domain controller and a member 2008 server.
When trying to promote the member 2008 server via DCPROMO, it gets to the point examining active directory forest and then a message you will not be able to install a writable replica domain controller because the RID master oldservername is offline do you want continue ? (The Oldservername no longer exists on the LAN. )
It then examines DNS configuration - comes back with
You cannot install a read-only domain controller at this time. You must first run "adprep /rodcprep" from a command window on any computer in this forest. The Adprep utility is available on the Windows Server 2008 R2 installation media in the \support\adprep folder.
Clicking next reveals "you cannot install an additional domain controller at this time because the RID master Oldservername is offline."
What is safest way please to remove the ghost oldserver from the domain ?
thank you

Run netdom query fsmo
You won't be able to transfer them, you have to seize them, you have no other choice.
If it's been like that for years I'd recommend being near a toilet, if it goes wrong you'll want to throw up.

Hi,
Is your current domain controller holding all the roles? run netdom query fsmo and see if it list all the 5 roles pointing to your current DC? then perform netdom query dc . Is the old DC appears here?. If the old DC no longer present in the network and the current DC holding all the roles, then simply performing the Metadata cleanup would do the job for you.

All the other roles are still pointing to oldservername after above command - so Ive tried just seizing RID and rerun DCPROMO on other server ! Gets further now - "A delegation for this DNS Server cannot be created because the authoritative parent zone cannot be found
or it does not run Windows DNS Server. If you are integrating with existing DNS infrastructure you manually create a delegation to this DNS server in parent zone etc etc -
Apparently safe to continue and has completed - as for the rest maybe I'll let sleeping dogs lie ....
