What happens if you open a command prompt (start > run, type cmd , press enter), and type in: ping fs2netd.game-warden.com
and press the enter key? I don't expect the ping to work, but what does it say about the host? Specifically, you should be getting: Microsoft Windows XP [Version 5.1.2600]

If it won't return the [64.92.160.250], then there is a problem with your DNS like karajorma said. Try typing in ipconfig /flushdns and hitting enter, then pinging again.
