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.
Click the tab labeled "Connections." In the new window, click the button labeled "LAN Settings." A new window opens that displays your current proxy server settings.
View the information in the "Proxy Server" section for your LAN settings. Your proxy server's full name or IP address is displayed in the text box. Click the "Advanced" button to view more information. This window displays the protocols used on the proxy server such as FTP and HTTP.
Click the "Cancel" button to close the window without making changes. If you want to remove the proxy server settings, remove the check mark in the box labeled "Use a proxy server for your LAN."
Open Firefox and click the menu item labeled "Tools." Click the "Options" item at the bottom of the menu.
Click the "Advanced" icon at the top of the settings window. In the window displayed, click the "Network" tab.
Click "Settings" in the section labeled "Connections." In the window opened, the proxy server's IP or full name is displayed. Click "Cancel" to close the window if you do not want to make changes. To remove proxy server settings, select "Direct connection to the Internet" and press "OK."
