It's strongly recommended that you have more than one DC. However, I would
not set either of the two as a DC.... I'd recommend getting a 4th box and
making it your second DC. You don't need high end servers to run as a DC. If
configuration is still an option and cost is an issue, I'd look at lowering
the specs fo r the first DC so that having two wouldn't be that much more...
BTW, with W2K and W2K03, there is no PDC/BDC designation. There are 5 FSMOs
(roles) that are assigned to one or more DCs. The first DC automatically has
all 5. If you have more than one, you can move or add some to the other DCs
to provide redundancy.

Roaming profiles normally reside on a separate server. It would make most
sense to have them reside on a file server. Be careful with workloads. You
should consider multiple drives on the DB/file server with separate
channels. At least the drive with the files (and profiles) being served
should be separate from the drives with the databases and log files. It
definitely should be on its own channel. Otherwise, file serving will have
an adverse effec ton the DB perfoemance....

Roaming profiles don't require AD. *Profiles* only make sense if AD is
intalled. AD is only on a DC. When you make a server a DC, it automatically
has AD. All you are really doing with roaming profiles is putting them on a
different server so that a user gets the same profile regardless of where
they log on.
