My daughters laptop has a problem .. she is using vista and no matter which browser firefox or IE she gets a screen that says Proxy server can not be found. I dumped IE in hopes it was causing the problem but to no a wail
She may have installed a hide ip type program for security most likely. Which connects to a proxy server then that proxy server goes to web address's she wants and resends data to her.
Might look in the Control Panel at 'Internet Options' 'Connections' LAN button and uncheck the proxy server. And/Or find and uninstall the hide ip proxy program she installed.
Thanks Mikie, I went there and I checked auto detect for proxy server and that looks like fixed the problem
