Since the application works when the FW client is disabled, it's not a
policy problem.
More likely, it's name resolution.
FW client apps depend on the ISA to make the external connections, and also
to perform name resolution.
You can prove this by:
1. disable the FW client
2. open a cmd window
3. "ipconfig/flushdns"
4. ping <externalserver>
- what is the response?
5. ipconfig/flushdns
6. enable the FW client
7. ping <externalserver>
- what is the response?

Hello Jim
Yes the application is "Outside" the firewall - they launch a program
that in turn is meant to communicate to a company outside of the
firewall.

The FW client should actually help the app communicate across the
firewall unless you have rules in place denying all except sepcified
protocols (good policy, BTW).
Are they trying to communicate inside-to-inside, or are they trying to
cross the firewall?

Hi everyone
I think I am going completely mad!!
I have a 3rd party application that communicates on Port 319 - If the
users Win2k Workstations Firewall Client are enabled, the application
does not respond. If they disable the firewall client, the program works
fine.
Can someone tell me where I need to enable port 319 through the firewall
please?
Thank you so much..... I think I am losing it :-(
Simon
