This proves that you have IP connectivity to the Internet.

XP has a firewall, that's probably why you can't ping it. Also, it's not uncommon for people to disable ping responses on DNS servers. So pinging may not be the best test.

Try defining 4.2.2.3 as a DNS server. I've used that before for testing as well.

It sounds like your biggest problem may be DNS.
