Firewall Client/Proxy Server Question

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

We are using SBS2000 --with ISA Server 2000. We only have XP Clients.
Is there any reason to have both the Firewall Client and the Proxy
Server setting in Internet Explorer set to point to the ISA Server at
port 8080? Or, is the the Firewall Client alone sufficient for
Internet browsing? We think that setting the proxy setting is ony
necessary if for some reason (such as the OS or browser in use) the
Firewall Client cannot be installed.

As it is now, we have both. However, periodically, but very
infrequently, at random websites, the user is prompted for a username/
password for the Proxy Server. If we remove the proxy settings, the
prompts do not occur, but we sometimes get "page cannot be displayed"
or similar error. We are not sure why we are prompted as the same
webpage may or may not prompt the user?

Thanks.
