The information in this article applies to:
When you try to connect through Microsoft Proxy Server 1.0, your Web browser may display the following error message:
The Proxy Server has encountered an error (The access code is invalid).
This error message is returned when you try to access the proxy server from an invalid interface.
For example, if the Proxy Server is connected to your internal network and the Internet and the Web browser resolves your Proxy Server's IP address to the Internet IP address instead of the internal IP address, you will get the above error message.
You can also get the above error message if the internal network protocol is IPX and the 10.0.0.0 through 10.255.255.255 addresses are not configured in the Local Address Table (LAT).
Verify that the Local Address Table (LAT) contains only the IP addresses of your internal network clients (including the IP address of the internal network card on the proxy server).
Verify that your web clients are resolving to the address of the intranet network card. To test, PING your Proxy Server’s name or DNS name and make note of the address that is returned. If the address belongs to the Internet network card, correct it by checking your WINS server, DNS server, or LMHOSTS files.
