I just recovered my main Windows 2000 domain controller into a test environment to test my disaster recovery procedures. I have two domain controllers in my live environment, but this server holds all of the FSMO roles. I used Arcserve 9.0 to recover the server onto a new box and restore the active directory with an authorative restore. The problem I am encountering now is that I keep getting an event id 16650. I've searched the web and found instructions to add authenticated users and another group to the local security policy, but that does not seem to correct the problem. Although I am recovering in a test environment, I'd like to ensure that in the event of a real disaster, I would be able to restore both of my domain controllers and have them sync up and continue to provide authentication to the domain. Any advice would be greatly appreciated.
