cannot access Rails server

I've installed a fresh version of ruby and RoR on a Win XP. I run WEBRick server and everything seems Ok but I can not access http://0.0.0.0:3000 from the browser. I've tried to ch开发者_如何学Cange the port to 80 but still have the same problem, even ping gives a "cannot find host" error. Any clue guys?

Try http://localhost:3000, that should work.

Have you tried http://127.0.0.1:3000/ or http://localhost:3000/ instead?
