In the last few months I have added 2 new DC's (Windows 2003 x64 SP2) All running fine. I moved the roles successfully off my old WIndows 2000 DC that had all the roles amd made them both GC's. I demoted that win2k DC and took it offline about 3 months ago.
I have one old WIndows 2000 DC that was a GC thats all. Obvioulsy I have to uncheck GC in AD sites & services before I demote this. However when I do this all my outlook clients lose ability to send mail and the Address list disappears.
I have seen articles which manually tell the clients to use a specific GC with a reg hack such as
But It seems crazy that I have to do this on 100 clients, this old server is just a waste of electricity.
Anyone have any ideas of how I can get my clients to talk to the New DC's that are GC's ?
