KB ID 0001453 Problem I was trying to demote a domain controller yesterday morning, it was a 2008 R2 Domain controller, (in fact it was SBS 2011). I’d already added a nice new Server 2016 Domain Controller to the domain, and transferred all the FSMO roles, so I was surprised when I tried to gracefully demote the old DC and got this; You did not indicate that this Active Directory domain controller is the last domain controller...
