Operating in a Win XP SP3 environment. When opening a specific website the browser reports it can't find the site. When I open IE or Chrome I get the same.
Running an IE diagnostic indicates that access to HTTP, HTTPS and FTP ports are blocked. Using tools outside the browser can ping those ports so it appears that the restriction is only when a browser is accessing those ports. Reboots can, but not always, clear the problem. Once fixed one can browse normally until you hit that one site. Does not appear to have the same problem on Win 7.
Can you try this one go to the option and network setting and choose no proxy
