Hi Ben,
I wasn't trying to goad you (yet) into installing the Firewall client.
What I was trying to determine is if the clients were configured as Web
proxy clients. Since Web proxy clients are configured to forward
connections to the Web proxy service, and if the Web proxy service has a
rule that allows outbound HTTP, the ISA firewall doesn't care what port
the destination HTTP connection is made on, all it cares about is HTTP.
So, you don't need to create a new protocol definition to support the
Web proxy clients. I suspect what happened was that when you installed
the Firewall clients, the Web proxy client configuration took place
automatically and that's why things worked (IIRC my ancient ISA2k
knowledge).
HTH,
Tom

O.K., I went ahead and installed the Firewall Client on the
workstations that needed to access this site and that works fine. Good
enough - like I said, only maybe 2-3 workstations in the whole org need
to access this site so it's fine.
Thanks!

Hi Ben,
Are these Web proxy clients that are having the problems?

http://www.ISAserver.org
I've Googled this and tried a few things (like adding
the SSLPortListMembers registry key) but so far with zero success. I
have a client who's LAN is behind an ISA 2000 box. They need to access
a website that is located on port 81 but it simply won't connect to it.
I tried creating a protocol definition for it, but no luck. Any tips
would be appreciated.
The site they are trying to reach is in the format of:
http://server.domain.com:81/sites/directory/page.aspx
And it works fine for machines at other sites who are
not behind this ISA 2000 box so I assume it's ISA blocking the access.
Thanks for any suggestions.
