Proxy Client Cannot View External Web Sites

ID: Q195257

The information in this article applies to:

Microsoft Proxy Server version 1.0
Microsoft BackOffice Server version 4.0
Microsoft Windows NT Server version 4.0
Microsoft Windows NT Server, Enterprise Edition version 4.0

SYMPTOMS

You may not be able to view external Web sites from a computer using Microsoft Proxy Client software on a network connected to the Internet through Microsoft Proxy Server 1.0. Although you can view Web pages located on the Proxy server from a network client, and you can browse the Internet from the Proxy server, you are unable to view external Web pages on a computer using the Proxy Client software.

CAUSE

This behavior can occur if the Proxy server or the network client is configured incorrectly.

RESOLUTION

To resolve this issue, verify that the Proxy server and network clients are configured correctly. To verify that your Proxy server's configuration to properly communicate with both clients and your Internet service provider is correct:

Ensure that the Proxy clients are communicating with the Proxy server by running the Chkwsp32.exe program located in the clients' C:\Mspclnt folder.

Verify that the Enable IP Forwarding check box is not selected in the Proxy server's network configuration. To confirm this, click Start, point to Settings, click Control Panel, and then double-click the Network icon. Click the Protocols tab, click TCP/IP Protocol, click Properties, and then click the Routing tab.

If the Proxy server has the Remote Access Server service installed, configure the automatic dialing feature for manual startup. You can do this by clicking Start, pointing to Settings, clicking Control Panel, and then double-clicking the Services icon. Double-click the Remote Access Autodial Manager service. Under Startup Type, click Manual, click OK, and then click Close.

Verify that the correct credentials are being used for the user name and password in the Proxy Server Autodial configuration. To confirm this, click Start, point to Programs, point to Microsoft Proxy Server, and then click Auto Dial Configuration. Click the Credentials tab.

If you check and confirm that the settings listed above are correct but a client still cannot view external Web sites on the Internet, you may want to try basic network troubleshooting.
