I have a new exchange server 2003 connect to an old Domain Controller. I want to get rid of the old DC and have exchange and DC on one box, on the new exchange box.How do I promote the exchange server 2003 to Domain Controller with out breaking the exchange server and git rid of the old DC server?

Strictly not recommended and supported. This can put in a tight fix and can remove the basic functionalaties of the exchange server.http://support.microsoft.com/default.aspx/kb/822179/en-ushttp://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/2003_Server/Q_24035327.htmlRaj

I agree, this is not a supported production configuration and would not recommend doing it.Mark Morowczynski|MCT| MCSE 2003:Messaging, Security|MCITP:ES, SA,EA|MCTS:Windows Mobile Admin|Security+|http://almostdailytech.com
