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. To do this, follow these steps:
