Issues with demoting a DC from domain.
When running DC Promo, I get the follow error: "the directory service is missing mandatory configuration information, and is unable to determine the ownership of floating single-master operation roles"
FSMO has been transferred previously, using the AD snap-in referenced in this web link: http://www.elmajdal.net/win2k8/Transferring_FSMO_Roles_in_Windows_Server_2008.aspx
However, I did note that the Infrastructure Master in the ForestDNSZones has an orphaned entry for a failed DC which was forcefully removed. ADSI Edit shoes the entry as:
50b68,CN=<Failed Sever Name>
I've tried remove the "\0ADEL:cfa48360-9c4e-456b
10a50b68" string on the NTDS Settings completely and changed the server name to the right server but to no avail. Should I be changing the NTDS Setting and what should I cange the \0ADEL into? What does it mean?
Seems there some metadata lingering around but not sure where else to look. Any help would greatly be appreciated. Thank you.
