I have a Xenapp 6.5 farm (1 server) Windows 2008. I have a published Internet explorer 10 application for a website application. I have created GPO for the internet explorer settings, zones, trusted sites, pop-up blocker etc.. Its all working except the Trust Zone security template. I have it set to low and when you run the published app in Citrix it reverts to medium. I ran a gpresult and it says my GPO was applied. Also I am trying to disable the popup blocker on this as well and that setting is not saving. Any ideas?
