There was an old 2008 DC that was mainly used for DR purposes which died some time ago. It had no FSMO roles. I wanted to try removing it from my AD but, when I try and delete its entry in Users and Computers, I am getting an "access denied" error. I checked and the "Protect object from accidental deletion" checkbox is unchecked for that DC in Sites and Services so now I don't know what to do. Any ideas?
