Q: When attempting to add some website to our Windows 2012 R2 server, the Trusted sites is grated out and i can’t add them. Why?
chicagotech.net: You may want to check the group policy settings. Go to ser Settings -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page. If it is enabled, the Trusted sites will be grated out. If you don’t want to disable it, you can modify policy Preferences Registry Items to add the websites. Please refer to this link:
