Sorry, I realized I put the 1st post in the wrong category. And didn't see any obvious way to delete or fix it.

We recently turned on authorization on our ISA proxy server which initally broke every 3rd party internet application. Only MS software would work as it would respect the proxy settings set in IE > Tools > Internet Options > Connectionns > LAN Settings. (you can also access Internet Options in the Control Panel of course) After a day we realized that 3rd party apps don't support encrypted auth to the proxy server so we turned off encryption and that fixed some applications. But currently we can't get Yahoo Messenger nor WebDrive to work through the ISA proxy. Any ideas?
