I did my first SBS 2003 R2 install a couple of weeks ago on a Dell PE 1900
with dual duo core processors. Everything worked fine until I installed ISA,
at which point the ISA service failed to start on boot up. The error message
led me to a MS KB article that said the license for ISA on SBS is limited to
2 processors but the system will interpret 2 processors with hyperthreading
as 4 processors. The fix was to disable hyperthreading in the BIOS. Not
sure if that is essentially walking my system capability back to an
undesirable level but it fixed the ISA service problem and I still see 4
processors in the Task Manager.

I don't actually know how a bios disabled HT impacts the system, but, I
would have opted for a Single NIC solution with a hardware firewall
appliance (not talking about a NAT router).
