DCPromo out fails with: The directory service is missing mandatory configuration information, and is unable to determine the ownership of floating single-master operation roles.
While trying to demote, dcpromo out, a domain controller the operation might fail with the following error
"The directory service is missing mandatory configuration information, and is unable to determine the ownership of floating single-master operation roles."
As you can notice, in my case, the partition at problems was DC=ForestDnsZones,DC=domain,DC=int.
