I've enabled following rules in ISA server. Protocol rule. 1. Protocol- HTTP, HTTPS, FTP (Download only). For all request. Allow site and Content rule. 1. Destination- any. Applies to - proxy_user_group(users). Allow 2. Destination- any. Applies to - allowed_computer(allowed client set). deny. Using these rules I'am allowing our people to browse with user authentication and also from designated desktops. Now I also wan't to allow specific URL(www.microsoft.com) to everybody without user authentication and from all the desktops. Can anyone tell, how to enable this? Suggestions will be reciprocated with many more thanks.
