Has anyone encountered this problem with IE7? Our site has Windows XP 2 SP2 with all of the lastest updates:
Originally a GPO was created to add a few sites into IE6 Internet Options/Security/Trusted Sites/Sites. The path in the GPO as follows: Computer Config/administrative templates/Windows Components/Internet Explorer/Internet Control Panel/Security Page/Site to Zone assignment list
After the installation of Internet Explorer 7 the sites defined by the GPO appeared under Internet Options/Security/Trusted Sites/Sites in the zone as they normally do. However, we discovered that sites cannot be manually added in because the buttons have been greyed out. Before the Trusted Sites Zone was accessible with Internet Explorer 6.
We checked and there are no other top-level GPOs that are inherited.
Is this a known issue with IE 7 or some sort of bug?
