Ah that gives us a better idea, to me just leave it as it is until you move to exch2007 or when you look at replacing the hardware.

Have only been here 3 days. They do have multiple domain controllers. So if exchange tanks we can start over pretty easy. Just gettting my reasoning lined up before I have to face that moment. 2 physical sites with 2 dc's at each site plus the exchange server/dc. Don't have total on servers, but less than 65. users above 80 and will be aproaching 120/150 by end of next year.
