This information applies to Windows Internet Explorer 7 and Windows Internet Explorer 8.

The proxy settings are used to tell Internet Explorer the network address of an intermediary server (known as a proxy server) that is used between the browser and the Internet on some networks. In general, you should change the proxy settings if you are connected to the Internet through a corporate network. By default, Internet Explorer automatically detect proxy settings. However, you may need to manually set a proxy with information supplied by your network administrator. Here’s how:

To change the proxy server settings

Open Internet Explorer, click start the Start button, and then click Internet Explorer.

Click Tools, and then click Internet Options.

Click the Connections tab, click LAN Settings.

Activate the checkbox Use a proxy server for your LAN.

In the Address box, type the address of the proxy server.

In the Port box, type the port number.

If your network requires separate proxy addresses for different services, such as HTTP, HTTPS or FTP, click the advanced button, then type the individual addresses of proxy server to use.

When you have completed your changes, click OK until you return to Internet Explorer.

If you follow the steps to change proxy server settings and still you find that the address you type for a new proxy server is not saved, verify the following:

If you enter a URL (Uniform Resource Locator) or Internet address for the proxy server, make sure that you are using forward slashes (/) rather than backslashes (\) when typing the address. For example, you must type http://servername and not http: \ \ servername.

If you enter a naming convention or a local network address for the proxy server, make sure you use backslashes (\) instead of forward slashes (/). For example, you must type \ \ servername, not / / servername.
