I am running through Dcpromo but I am unable to remove a domain controller.
This is a multi Site domain with a mix of 2008 r2 and 2012 r2 DCs.
The error message is:
Active Directory Domain Services could not transfer data in directory partition
The directory service is missing configuration information and unable to determine the ownership of floating single-master operation roles
It is an old server and is being removed. Any changes it might have are not important.
