Right. Does he get a timeout, does he get a "500 page not found" error,
etc.?

If it's taking a long time to come up, do "netstat -an | findstr <ip>"
while the browser is hanging -- see if the connection is in SYN-SENT or
ESTABLISHED state. This tells you whether the problem is with basic
communication (blocking the SYN packets) or something else.

For even more advanced troubleshooting, download the Wireshark network
analyzer to see the whole sequence of packets to/from the site.
