Can't Access application config file with APPSETTINGS through fire

We have a client with an ISA Server 2000 configured in cache only mode, and a
checkpoint one firewall. Integrated authentication is required for requests.
We can replicate the problem with an ISA Server 2000 configured in integrated
mode, with integrated authentication required, and the Web Proxy used. The
problem is this:

We have a no-touch deployment client side .NET application configured at a
URL. When navigating to this URL, the application downloads with no problem,
but all access to APPSETTINGS to retrieve application settings fail - they
return blank values. If we disable use of the Web Proxy on the ISA server on
our replicated setup, everything works. This is not an option on the client
site.

The problem appears to be that the behind-the-scense XML requests used by
the .NET framework to access the app.config file are sent as anonymous
requests, which are blocked by the firewall.

Is there a solution to this one?

Any help appreciated.
