The Internet Explorer Enhanced Security Configuration component configures a number of security settings that define how users browse Internet and intranet Web sites on the server. By default, the Internet Explorer Enhanced Security Configuration component is enabled in Microsoft Internet Explorer on Windows Server 2003-based computers. The settings limit the types of content that a local user can view by using Internet Explorer, and help prevent local users from downloading harmful files from the Internet. The Internet Explorer Enhanced Security Configuration settings do not affect remote users who view content on the server.
