We have two domain controllers in two different states.
Sydney has the Primary Domain Controller which is running all the DC roles (2003)
Melbourne has the secondary Domain Controller (2008) which has been disconnected from the VPN for over a year (due to another IT firm)
We wish to demote the Melbourne DC the best way possible.
During this Tombstone period - the IP configuration has changed from 192.168.0.x/192.168.1.x to 172.20.x.x/172.30.x.x in both states.
We now have the VPN back up and running (and have a PPTP VPN connection worst case)
What would be the best way to demote the secondary DC in Melbourne?
I was hoping not to use the force command if possible... but open to suggestions.
