Yes, Exchange can run on a domain controller and/or a server that has shared
folders as well. I don't know how large your user community is, but I have a
client with about 175 users who has no problem with this setup in a
production environment. They do have a secondary domain controller, but it's
a small box that doesn't do anything else.
As in most situations, the more horsepower your server has in this case the
better. Hardware RAID, gobs of RAM (1GB+), multiple processors, etc. make
this more feasible. The actual requirements depend on the size of your user
As an aside, for disaster recovery you should also consider a backup mail
service. For about $10/yr you can have someone like Zone Edit
(http://zoneedit.com) be an alternate SMTP server for your domain. They will
hold the mail and when your server comes back up the mail will be delivered.

In our production environment, we have separate domain controllers and mail
(Exchange 2000) server. We are deciding what servers are necessary in a
disaster-recovery environment. We don't see a need to replicate each &
every server at the warm site, so we are exploring what functions can be
That said, will Exchange 2000 play well on the same server as a domain
controller, and possibly serving shared folders as well? (If it matters, we
are running Active directory in a single-domain setting).
