Like Robby, I have no idea what is wrong. But to help isolate it, you might try:

>From a terminal

> telnet www.google.com 80

The enter

GET / HTTP/1.0

and press return twice. You should get a 200 or 302 response.

Then try the same from Drscheme. Something like [untested]:

(require net/url)
(read-line (get-pure-port (string->url "http://www.google.com/")))

If you see the same response something is wack with accessing Planet
(maybe a firewall?) If you don't see the same response probably
DrScheme is not picking up some system wide network configuration.
