Configuring Zones on the Local Computer

You can configure the exact privileges assigned to each of these security zones by following these steps:

1. Select Internet Options from the Tools menu.
2. In the Internet Options dialog box, click the Security tab.
3. Click the zone you want to modify. In the Security Level For This Zone group, move the slider up to increase security and decrease risks, or move the slider down to increase privileges and increase security risks for Web sites in that zone. For more precise control over individual privileges, click Custom Level. To return to the default settings, click Default Level.
4. Click OK to apply your settings.

Note Application developers can use the IInternetSecurityManager::SetZoneMapping() method to add sites to specific security zones.

To configure the Web sites that are part of the Local Intranet, Trusted Sites, or Restricted Sites zone, follow these steps:

1. In Internet Explorer, visit the Web page that you want to configure.
2. Select Internet Options from the Tools menu.
3. In the Internet Options dialog box, click the Security tab.
4. Click the zone you want to modify and then click Sites.
5. If you are adding sites to the Local Intranet zone, click Advanced.
6. If you are adding a site to the Trusted Sites zone and the Web site does not support HTTPS, clear the Require Server Verification (HTTPS:) For All Sites In This Zone check box.
7. Click Add to add the current Web site to the list of Trusted Sites. Then click Close.
8. Click OK to close the Internet Options dialog box. Then close Internet Explorer, reopen it, and visit the Web page again. If the problem persists, repeat these steps to remove the site from the Trusted Sites zone. Continue reading this section for more troubleshooting guidance.

You need to add sites to a zone only if they cause problems in their default zone. For more information, read the section titled "Troubleshooting Internet Explorer Problems" later in this tutorial.
