Oke my situation: Server: PIII 750 MHz 768 MB Running with: W2K Advanced Server, Active Directory, Exchange 2000, DHCP, DNS, ISA Server 2000 and file and print service. Yes it's al running on one machine! I have only 2 users and I think with 15 users it can be easily done, but then again like Anthony: In theory, there is no difference between theory and practice. But in practice, there is. But if the company isn't going to kill you if something is wrong with the server, I say: go ahead!!!

Although it can be cheaper to do it that way in the short run (one box, many tasks) if they *are* planning on growth, its going to hurt them a lot more when its all got to be re-installed again. I don't know what the others will recommend, but I'd be asking for a box for Exchange by itself with a number of HDD's in it, and perhaps DC + ISA on the other box. If they insist, make sure that you've got them acknowledging that you don't suggest doing it this way. In theory it might work ... but look at my .sig :) -- Anthony Michaud Network Administrator Act!
