A. Windows 2003 introduces the IE Enhanced Security Configuration and enables this configuration by default for all users and groups. This locked-down configuration protects your computer from exposure on the Web by initially blocking connections to most Web sites, although you can add any Web sites that you regularly visit as part of a trusted zone. By default, the IE Enhanced Security Configuration considers the Windows Update and Error Reporting Web sites, and not much else, as trusted sites.

To add or remove the IE Enhanced Security Configuration feature from Windows 2003, perform the following steps:

  1. Start the Control Panel Add/Remove Programs applet (go to Start, Settings, Control Panel, and click Add/Remove Programs).
  2. Click Add/Remove Windows Components in the left pane of the dialog box.
  3. Scroll down to Internet Explorer Enhanced Security Configuration and select the check box to activate the locked-down configuration or clear the check box to deactivate the locked-down configuration.
  4. If you're enabling the locked-down configuration, click Details to select which users (e.g., administrator groups, all other user groups) you want the policy to apply to.
