Want to Use ISA with 2-NIC

Relative novice here, so please forgive...

We currently have the following config:
-Single NIC server box running AD, DNS, DHCP, IIS
-192.168.16.x internal IP range (very small network)
-Sprint ADSL modem/router (internal IP addy 192.168.16.1 with an external
static IP address)
-24-port hub
- The server, the DSL router and all workstations connect to the hub, the
DSL router via a crossover cable.
-Default gateway is 192.168.16.1
-Internal NIC and DNS address is 192.168.16.2
-Network is great, Internet connectivity is great.

My goal is to run ISA so we can use the firewall feature and to point a
registered domain to our static IP. I installed a second NIC to be able to
run ISA. There are conflicting articles with MS about how to configure the
second NIC and ISA and have tried various combinations. But when I install
ISA, my internet connectivity goes away.

I configured the second NIC as:
IP address = the static external IP address assigned to us by Sprint
Default gateway = the gateway address supplied by Sprint
DNS server = 192.168.16.2 (I also tried using the DNS servers supplied by
Sprint)

Then, configured ISA:
IP address = the static external IP address assigned to us by Sprint
Default gateway = the gateway address supplied by Sprint
DNS server = the DNS servers supplied by Sprint

Then connected the DSL router to the second NIC via the crossover cable
(also tried a regular CAT5 patch cable).

I also tried to run ICW, but it stops with an error message, and the
icwlog.txt shows an error returned from call to RegisterMSBOExchangeBP().

No matter what I do, I have to return to my original configuration to have
internet access. I have searched MS and this newsgroup, but can't find any
solution that helps. Thanks in advance for any advice.
