The strange thing is I can telnet to multiple POP servers from the server
and
one workstation on the network, but not from any other ones. I checked the
config of that one workstation and it is identical to the other systems.
We
are using multiple versions of Outlook, but the oldest version is Outlook
2000. I tried the logs and they really are hard to dicypher. I have tried
installing the Firewall client on several workstations and that didn't
help
either. At this point I am on the verge of moving to a new server,
dropping
SBS 2000 / ISA all together, and getting a Sonic Wall of something.

What you need is ISA2004/6 in place of ISA2000. SonicWall doesn't have a
prayer of doing all the things ISA can do with the flexability that ISA can
do them. But you'd have to install ISA on its own machine and stop using
the SBS machine as the "firewall". Run the SBS with one nic like any other
machine on the LAN and remove ISA from it.

Back to the workstations,..if one works and one doesn't then ISA is working.
The workstations may appear to have the same config,...but there has to be
something different about them that you are missing. The other possiblity
is that you haven't looked closely enough at your Rules on the ISA and you
don't have what you think you have.

And...
Like I said before, Outlook (not Express, and version irrelevant) by default
does not use the Firewall Service on ISA. That means the Rules have to be
anonymous and based on the Client's IP#s. If you don't want it to be
anonymous then you have to adjust the Firewall Service on ISA so that
Outlook will use it. Outlook will *not* ever work with the Web Proxy
Service, a CERN Compliant Web Proxy Service does not do SMPT/POP3. The
three services of ISA follow the Industry Standards for how such services
are supposed to function,...so you have to follow the standards too.
