Please start Internet Explorer, and when the program is open, click on the Tools menu and then select Internet Options.

• Now click on the Connections tab and then the Lan Settings button
  
• Under the Proxy Server section, please uncheck the checkbox labeled Use a proxy server for your LAN. Then press the OK button to close this screen. Then press the Apply button and then the OK button to close the Internet Options screen. Now that you have disabled the proxy server you will be able to browse the web again with Internet Explorer.

That was easy enough. Thanks for all your help!
