Proxy servers allow you to use another web server as a gateway to the Internet. Some business networks use a proxy server to funnel traffic through the gateway. It gives the administrator control over bandwidth usage, and inappropriate websites can be blocked. Proxy server settings are found in the web browser settings. Using Internet Explorer or Firefox, you can view your current proxy server and disable the settings.
Open Internet Explorer. Click the "Tools" menu item and select "Internet Options." A new window opens where you can view all your current Internet Explorer settings.
