Current setup is 3 exchange 2010 servers. One of these servers in a DC (exch3) and I'd like to correct that problem as there is finally another 2008 DC available in the site. There are no current active DBs on exch3; it is just used to hold copies. I want to keep exchange on the server but remove AD. All FSMO roles have been transferred to the new DC and there is a GC available. Is it as simple as DCPromo'ing it down? Thanks

Thanks to both of you. I was really hoping that wasn't the case...
