Note: The Internet Explorer 11 desktop application will be retired and go out of support on June 15, 2022 (for a list of what's in scope, see the FAQ). The same IE11 apps and sites you use today can open in Microsoft Edge with Internet Explorer mode. Learn more here.

Symptoms

A computer that has Windows Internet Explorer 7 installed is running Windows Vista, Microsoft Windows XP, or Microsoft Windows Server 2003 in an Active Directory domain environment. However, the Add button in the Trusted sites dialog box is unavailable. You cannot add a Web site to the "Trusted sites" zone even when the current user account belongs to the Administrators group.

This problem occurs if the "Security Zones: Use only machine settings" Group Policy setting is enabled.

Note When Microsoft Internet Explorer 6 in installed, members of the Administrators group can configure the "Trusted sites" zone regardless of whether the "Security Zones: Use only machine settings" Group Policy setting is enabled.

Cause

This problem occurs because the behavior of the Internet Options dialog box has changed in Internet Explorer 7. When the "Security Zones: Use only machine settings" Group Policy setting is enabled, you cannot use Internet Options to configure zone settings.

Resolution

After you apply this hotfix, the system determines whether the current user account belongs to the Administrators group. If the current user account belongs to the Administrators group, the user can add Web sites to the Trusted site zone regardless of whether the "Security Zones: Use only machine settings" Group Policy setting is enabled.
