title: Ping fails but http link works
body: <p>In one of the system (Windows), if I ping to a particular public forum site, [lets say testsite.com here], then I get a request timed out message. However, if I just put that site address in the browser (used IE6, but its not specific) with http://, then the link works fine and the browser goes to the web page.
  What is it that the browser doing differently ?</p>
