Lanwench, thanks again for your input. I attempt to do as little maintainence
as possible during the work hours of course. However 2 of my clients are
large churches and they have extended hours 7 days a wekk plus some of the
programs they run require maintance by the software support personel during
the 8-5 time frame.
When I don't use ISA I typically intall a Sonicwall as my gateway and more
recently a newer firewall by Calyptix Security (it also has an internal hard
drive and will hold mail when the server is offline)

Lanwrench that is one the problem with the dual nic setup, The users
get to the internet thru the SBS box. If it is down, while they can
log on to their own box they have no access to the outside world. I
am looking for a way to make my systems a little more "bulletproof"
and at the same time allow me to do some server maintainance without
totally shutting down the office.
Well, I don't think you should be doing server maintenance during the
business day, myself - but your server shouldn't be the gateway if you don't
have ISA. Set all clients to point at your router's LAN IP as default
gateway.

In the past Most of my systems have been dual NIC usually with ISA

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.
Yes they can.....they just can't resolve names :)
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.
Yes. If you have another DC running AD-integrated DNS, and your
client workstations have the secondary DNS server listed, they
should work.
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.
You'd need to buy Windows 2000 or 2003 but I believe you wouldn't
need additional CALs.
That all being said, if you're having regular problems with your SBS
box going down, I'd rather address those - add as much redundancy to
the server hardware as you can. That would be a better use of money,
in my opinion, although it's true that outside of SBS, it's always
recommended to have more than one DC.
