Dial-Up Networking Connections Do Not Work After Upgrade to Windows XP

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: 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.
