Hi,

I can better help you with this if I can get some more specifics:

How are the offices connected? How loaded are these connections? How
reliable are they? How many users are at each office?

Exchage requires a beefy server, memory in particular.

In general, you're going to want DHCP at the head office, and possible at
satellite branches depending on connectivity. You'll have DNS on each of the
DCs, and configure clients to connect ot thei rlocal DNS server. Exchange
will be at the head office, more than likely.

2 Offices will be connected By cable modems with static
IPs the other 2 will Have dedicated T-1 Lines(all lines
have never gone down the two years the offices has been
here). The exchange server is beefy.we have 2 dual 2.8
xenon with 2Gb Ram 1tb storage the other two machines are
3 GHZ 2Gig Ram IDE raid with 360 Gb storage. each office
has 10 people. all locations will have a dhcp/dns server.
I have been told that all naming services can be run on
the same machine as long as they are on seperat
partitions and seperate drives if possible.
