Might have helped to tell us that originally.

ISA is blocking your access, so you need to configure ISA to allow
port 81 from your workstation/LAN to the internet/WAN. I don't know
what rules you have in place so it's tough to tell you what to change,
plus I don't know what company policies may require access being
blocked, if any. ISA is relatively easy to work with, if you look at
the docs you'll see how to handle most of this, and you could look at:

How to Allow Third-Party Internet Application Connections Through ISA

How To Safely Connect Your Company to the Internet in Windows 2000:;en-us;300876

Internet Security and Acceleration Server Support Center:

There's also an ISA newsgroup.
