A. Unlike with previous versions of Windows Server--in which you could disable Internet Explorer Enhanced Security Configuration by removing the component in Add/Remove Programs, Windows Components--the Windows Server 2008 implementation of Internet Explorer Enhanced Security Configuration is configured through Server Manager.
Select the root of the Service Manager navigation pane, and under the Server Summary click Configure IE ESC, which is part of the Security Information section. A dialog box appears, letting Internet Explorer Enhanced Security Configuration be enabled/disable separately for normal users and administrators.
