What kind of error message do you see on the clients IE?
*You might want to turn off "Show Firendly HTTP Error Messages"
Tools menu --> Internet Options --> Advanced

1. Is the Windows Firewall turned off in the Services?

2. Can people access a basic html page on your web server without having to go through any Exchange kafuffle?

3. Can the client computer telnet to one / all of your webserver ports via a domain name?(Windows) Start menu --> cmd --> run --> telnet www.yourwebaddress.com 80

4. Marines example has SSL links in it, so it probably is not a caching problem. but..  I have seen issue getting to / past the initial logon page, 401 errors. Turn off the proxy on the client for the sake of testing, or make a caching rule on the proxy not to cache urls containing.

e.g.

mail.domainname.com/exchange
servername/exchange

5. You might also want to check how IE is set to prompt for credentials.
Tools menu --> Internet Options --> Secrurity --> Custom Button --> Scroll to the bottom of list and check settings.
