I am using Security Zones and Content Ratings to make Security Level: Custom settings changes to Internet, Local Intranet and Trusted Sites. I am putting the URLs for trusted sites in "Site to Zone Assignment List" setting under "Administrative Templates/Windows Components/Internet Explorer/Internet Control Panel/Security Page" Also, under "Security Page" are all the settings found under Security Zones and Content Ratings for Security Level: Custom settings. What is the difference between "Security Zones and Content Ratings" and "Administrative Templates/Windows Components/Internet Explorer/Internet Control Panel/Security Page" for Security Level: Custom settings? Which one should I use to make the settings? Thanks in advance for your help, Norm
