I'm running a 2012 domain controller with Windows 7 PC's I have a proxy with various settings - we are using IE 9. Trusted sites are controlled via GPO. I have a website listed in my trusted sites in the GPO however, I have a user who when they try to access this site they get the following error: BIg Red X : Trust Not Granted - The application can not be depolyed because it is not trusted and possibly unsafe. I've checked the registry of the machine and the site is listed there with a 2 next to it for trusted sites. I've tried rsop.msc and it show up there too. I've tried resetting the web settings, removing the site from the registry and adding it back. I've even tried rebooting nothing, I mean nothing is working. I'm not even sure why or what the issue is since the site is clearly showing up in the registry of that PC. So if any can help it will be much appreciated. In addition, is there a way to unfilter the trusted sites and just add them manually instead of having to add it to the GPO??? Lastly this must use Internet Explorer so downloading Chrome, Firefox , etc is not possible.
