When you upgrade your Microsoft Windows Millennium Edition (Me) or Microsoft Windows 98-based computer to Microsoft Windows XP, your Dial-up Networking connections may not work as expected.

When you attempt to navigate through a Dial-up Networking connection, Microsoft Internet Explorer attempts to connect through a proxy server. If the proxy server is unreachable through the Dial-up Networking connection, you receive the following error message:
The Page cannot be displayed.
If the proxy server is reachable, the user's connection uses the proxy server unintentionally.


This behavior can occur if both of the following conditions exist:
  • Before the upgrade, the local area network (LAN) settings were configured to use a proxy server.
  • Before the upgrade, you had one or more dial-up networking connections that were not configured to use a proxy server.
This behavior occurs because the dial-up networking connections acquire the proxy configurations from the LAN settings during the upgrade.


To resolve this issue, remove the proxy server settings from the dial-up networking connections:
  1. Click Start, and then click Internet Explorer to start Internet Explorer.
  2. On the Tools menu, click Internet Options.
  3. On the Connections tab, double-click the dial-up networking connection under Dial-up settings to display the Dial-up networking connection Settings dialog box.
  4. Click to clear the Use a proxy server check box.
  5. Repeat steps 3 and 4 for each dial-up networking connection that is listed.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
