After you upgrade to Microsoft Internet Explorer 6.0 Service Pack 2 (SP2) in Microsoft Windows XP SP2, some SSL-secured (128-Bit) Web pages and Web sites may not work correctly. Frequently, this behavior is caused by security changes in Windows XP SP2. To determine why the pages do not display correctly, use the following methods in the order that they are presented.

Look for third-party firewall or antivirus programsMake sure that any third-party firewall or antivirus programs that are installed on your computer are configured correctly and are not preventing you from connecting to Web sites. For more information, see the product documentation or contact the program vendor.

Turn off the pop-up blockerInternet Explorer SP2 includes the ability to block pop-up windows. This new feature may block some Web pages. To turn off the Pop-Up Blocker, follow these steps:
Delete the contents of the Temporary Internet Files folderIf a copy of the Web page is in the Temporary Internet Files folder, the page may not display as expected. To resolve this problem, you must delete the contents of this folder. To do this, follow these steps:
Configure security, content, and advanced settings in Internet Explorer
Configure the security settings for the Trusted sites zone in Internet ExplorerNote Only add those sites that you trust as a trusted site. If you are not sure about a Web site, do not add the Web site to the Trusted sites list.
Reset the Security Zones to the default settings
Clear the Secure Sockets Layer (SSL) state and the AutoComplete history
Verify that Internet Explorer is configured to use SSL 2.0 and SSL 3.0
Use the System File Checker tool to scan all files that are protected by Windows File ProtectionUse the System File Checker (Sfc.exe) tool together with the /scannow parameter to immediately scan and verify the versions of all the system files that Windows File Protection helps protect. If the Sfc.exe tool detects that such a file was overwritten, the Sfc.exe tool retrieves the correct version of the file from the Dllcache folder or from the Windows XP installation source files, and then replaces the incorrect file. The Sfc.exe tool also verifies and repopulates the cache folder.
You must be logged on as an administrator or as a member of the Administrators group to run the Sfc.exe tool. To run the Sfc.exe tool together with the /scannow parameter, follow these steps:

Third-party browser extensionsSome third-party browser extensions and add-ons may interfere with how Internet Explorer views certain Web pages. To turn off these extensions, follow these steps:
Create a new user profileIn certain situations, you may not be able to search Web sites if your Windows user profile is damaged. To troubleshoot this, log on to the computer as another user and try to connect to a Web site. If you can connect to SSL- secured (128-Bit) Web sites when you are logged on as a different user, your user profile may be corrupted. In this situation, back up the information and settings that you want from your profile (for example, the My Documents and Favorites folders), and then delete the damaged profile.
