Currently I have 3 NT 4 servers.1 PDC, 1 BDC and 1 member. The PDC has Exchange 5.5, NAV for Exchange, M/S Proxy Server, WINS and DNS. I have 2 new boxes that I want to "split up the responsibilities" between. I have purchased 2K server and plan to purchase Exchange 2K. What would be the reccomendation on the split? I have my own ideas, but I thought I would get feedback before doing so.
