Dual NIC vs Single NIC



In the past Most of my systems have been dual NIC usually with ISA but due to
many reasons I am now considering going to a single NIC and moving away from
ISA.

Currently with my existing setup, if the SBS server is down, for what ever
reason, my customers can't even get to the internet.

If I had a second member server set up as the backup DC, a single NIC SBS
server, and a hardware firewall wouldn't that allow my customer to log on and
access the internet if the SBS server was offline temporarly? I would still
want the SBS server to run the DHCP and DNS roles but would assume that would
not matter as long as the SBS machine was not down for more than a few hours
at a time.

The above seems logical to me, but then since I have not done it I am
checking for any "gotchas" lying around that I might not be aware of.

By the way I would be running SBS2003R2 on such an install that would assist
me in the licencing issue of the second server which would be running server
2000 or 2003 as a member of the SBS box.
