WINDOWS

= SYMPTOMS =

When you try to use Microsoft Internet Explorer to connect to a World Wide Web site after a connection to the Internet has been established, you may receive one of the following error messages:


 * Could not open http://.
 * The Internet site was not found. Please make sure the address is correct. Could not open http://.

= CAUSE =

This problem can be caused by either of the following situations:


 * The World Wide Web site that you are attempting to connect to is outside the domain of your Internet service provider, and the TCP/IP protocol is not properly configured to use a default gateway when accessing a remote network.
 * The TCP/IP protocol is not properly configured to use a name (DNS) server.

= RESOLUTION =

To work around this problem, use the PING command to determine if the problem is being caused by incorrect default gateway settings or incorrect DNS server settings. To do so, type the following commands at a command prompt, pressing ENTER after each command:

cd ping

where is the name of your Windows folder. If a “Bad IP Address” error message is displayed when you press ENTER after typing the PING command, then this problem is likely being caused by incorrect DNS server settings. To work around this problem, see the DNS Server Settings section below.

If a “Reply from xxx.xxx.xxx.xxx: Destination net unreachable” error message is displayed (where xxx.xxx.xxx.xxx is the IP address of the site you are attempting to connect to) when you press ENTER after typing the PING command, this problem is likely being caused by incorrect default gateway settings. To work around this problem, see the “Default Gateway Settings” section of this article.

DNS Server Settings
If you are accessing the Internet using Dial-Up Networking, use the following steps to work around this problem:


 * 1) Click the Start button, point to Programs, point to Accessories, and then click Dial-Up Networking.
 * 2) Use the right mouse button to click the connectoid used to connect to your Internet service provider, and then click Properties on the menu that appears.
 * 3) Click Server Type, and then click TCP/IP Settings.
 * 4) Enter the DNS server settings provided by your Internet service provider.

If you are accessing the Internet using a proxy server or other LAN-based connection, use the following steps to work around this problem:


 * 1) In Control Panel, double-click the Network icon.
 * 2) Click the TCP/IP protocol, and then click Properties.
 * 3) Click the DNS Configuration tab.
 * 4) Enter the DNS server settings provided by your Internet service provider.

Default Gateway Settings
If you are accessing the Internet using Dial-Up Networking, use the following steps to work around this problem:


 * 1) Click the Start button, point to Programs, point to Accessories, and then click Dial-Up Networking.
 * 2) Use the right mouse button to click the connectoid used to connect to your Internet service provider, and then click Properties on the menu that appears.
 * 3) Click Server Type, and then click TCP/IP Settings.
 * 4) Click the “Use default gateway on remote network” check box to select it.

If you are accessing the Internet using a proxy server or other LAN-based connection, use the following steps to work around this problem:


 * 1) In Control Panel, double-click the Network icon.
 * 2) Click the TCP/IP protocol, and then click Properties.
 * 3) Click the Gateway tab.
 * 4) In the New Gateway box, enter the IP address of the gateway provided by your Internet service provider, and then click Add.

NOTE: If you are attempting to access the Internet using a proxy server, you may not need to configure the TCP/IP protocol to use a default gateway when accessing a remote network. To find out if your proxy server requires a default gateway, contact your system or network administrator.

If you are accessing the Internet using a proxy server, and the above steps do not resolve the problem, then the problem may be caused by incorrect proxy server settings. For information about troubleshooting proxy server settings, please see the following article in the Microsoft Knowledge Base:
