I recieved this error when attempting to open the AD Sites and Services console on Win2k3 Server. "The target principal name is incorrect". IThis machine was at one point an active DC on the Net. It was truned off for a long period of time (over 1yr.). I now can't access this console (AD Sites&Svc). Nor can I perform a DCPROMO to make machine a member first. I thought about a DCPROMO /forceremoval, but this will leave frags on all DC's...Right? I need some assistance as I want to have a redundant DC in my Root domain. I have a child DC doing something similiar, but I'd like to get this fixed and replicating first.
