I'm sure I'll be corrected if I'm wrong...this is how I'm envisioning it.
First...I'm envisioning that you have all the PC's (clients) running into a
switch as is your SBS machine. Then on a second NIC in your SBS machine you
have a cable running out and into your router then from the router to the
internet connection device (modem of some sort). Could you maybe just pull
the cable (catX) the goes from your switch to your SBS machine and run it
from the switch straight into the router? Turn on DHCP on the router.
Would that work? I know....BLASPHEMY! You're bypassing all the security!!!
Blah blah...if it's temporary...*I* would try it.
