I am in the process of removing a domain controller (2008 R2) from our environment. I was able to successfully transfer all required FSMO roles to the new domain controller, but receive the error when running DCPromo on the server.
"The directory service is missing mandatory configuration information, and is unable to determine the ownership of floating single-master operation roles."
I ran a dsquery using the command dsquery * CN=Infrastructure,DC=DomainDnsZones,DC=Domain,DC=com -attr fSMORoleOwner and receive the following output:
"CN=NTDS Settings\0ADEL:1d2ebcbd-16cb-4923-937d-ad768880ec2e,CN=OldServer\0ADEL:6fb18232-4b56-4646-ac5f-2809b5ee6a16,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=Domain,DC=com"
Based on the results of the command I see the problem is related to a role that's assigned to a server (OldServer) that was incorrectly removed from the environment over 4 years ago. While I believe i have identified the source of the
problem I have hit a wall on how to proceed with resolving the problem. Your advise would be appreciated..
