I have a customer with a very small, simple AD environment. One DC running Server 2008. Domain level Server 2008, forest level Server 2000. They requested a health check due to some odd behaviors. I found that the Infrastructure master is "Unknown". When I check the FSMO roles it simply states "Error" in the GUI. The below event is logged:
Log Name: Directory Service
Date: 11/14/2014 9:17:18 AM
Event ID: 2091
Task Category: Replication
User: ANONYMOUS LOGON
Ownership of the following FSMO role is set to a server which is deleted or does not exist.
Operations which require contacting a FSMO operation master will fail until this condition is corrected.
netdom query fsmo roles give the following instead of the proper distinguished name.
Infrastructure - CN=NTDS Settings\0ADEL:83aeeec3-ff1a-4046-bd72-ef5807175603,CN=
All other FSMO roles show ok and since there is only one DC, it obviously must host all roles.
I have no idea how long it has been in this state but the oldest log is from 11/2015.
My question: is there a risk of introducing stale objects or creating other problems if I try to fix this issue? The customer is actually wanting to just build a completely new forest/domain with server 2012r2 instead of trying to fix problems with this old environment.
Any comments or observations would be helpful.
