When a user tries to connect to a site witch uses java, not the whole screen is displays, the user is using Windows NT with IE 5.5, when i try to reach the site everything goes well, i'm using XP with IE 6, i need to turn off pop-ups for the site. I have created a rule for the site, so that the site can be reached anonymous, all the other sites needs to be authenticated. When the user tries again, there are no problems with the site, i have wrote the following rule: Name Overheid.nl Action Allow Protocols HTTP/HTTPS From Local,Internal To overheid.nl (domain name set) Users All Users Schedule Always I'm running ISA 2004 as a proxy server only.
