This is a very challenging one, so for all you it goeroes out there, here goes nothing.... ;)
I have a Citrix Terminal Server farm. They are located within their own OU and a policy is applied on this OU only. Off course the "local loopback processing" option is enabled. Now i have to add a site to the trusted sites, because ther's a Java applet that needs to be loaded. Users, while logged into the TS session, are not able to add their own sites to trusted sites, due to policies applied on the OU. So, policy freakisch as i am, i went to the user configuration --> Administrative Templates --> Windows Components --> Internet Explorer --> Internet Control Panel --> Security Page and added the site to the option "Site to Zone Assignment list" with a value of 2 (Trusted site value).
After doing a gpupdate /force on the TS and logging with a user, nothing happended, so unfortenately, it looks like the policy isn't applied. Does anybody have any idea why this doesn't work?? Or does anybody know why this happens (or does not happen??)
