Client has a windows 2003 domain with a seperate PDC box and another member server running windows 2003 and Exchange 2003.
The New Situation:
I just built a new PDC running windows 2008 to replace the old windows 2003 PDC.
Actually, the 2008 box is currently running as a member server until I can figure out the answer to my question below. Then I will promote it to the new PDC position and pitch the old PDC.
Since the Exchange box has taken years of tweaking to get it how the client likes it, I don't want to mess with it, like do a complete re-install. So what is the easiest and most reliable way (if there is such a thing) to re-associate the exchange server box to the new PDC. I'm not sure even where to begin since it's been several years since I set it up the first time round and now a new PDC with a different OS--HELP!
