I have a Dell laptop with windows Vista on it. A couple of days ago I downloaded a program for school called "NOTEPAD++". After the download, I noticed that, even though my wireless internet connection was good, ( I could view email and facebook), I couldn't access my school web pages anymore. The error message said, "your system is configured to use a proxy server but Google Chrome cannot connect to it. I followed the directions to disable the proxy, with no luck at all. I was not able to uncheck the box, "use a proxy server for your LAN." It also says some settings are managed by your system administrator." Please help.
With permission from BunoCS I would like to add a small step that might help. Please try to restore your computer to an earlier date when the Internet connection was working fine. Click here to find steps on how to perform System Restore in Windows Vista.
Hope this helps.
