We have 3 offices, US/UK/Moscow. we have 3 domain controllers in Moscow and US and 1 in UK. The office in UK has recently moved and the DC there was shutdown for about 3 months. during that time one DC in US was removed and another server was promoted to DC status. Now the DC in UK has been turned back on and it is not replicating with either US or Moscow and in the sites and services directory it still lists the DC which we demoted in US instead of the new server which was promoted to a DC. Question is: Can I run DCPROMO on the UK server, which was recently turned back on, in order to demote it and then re run it to promote it back to a dc so that replication will correct itself and hopefully sites and services will update. Because now our UK users are having problems logging etc... because of old passwords and such stored on the server which has not replicated since it was turned back on. Let me know what other info you may need please,I don't know how well I explained the problem.
