This is an odd one. My neighbor shares my wireless network and for some reason cannot browse any web sites as of last night.

DNS works because I can do nslookups and ping out. There is nothing in the hosts file except the localhost IPv4 and IPv6 entries. I checked that the firewall is allowing both IE and Firefox out and I also disabled it just to see if it was acting wonky. I'm out of ideas of what it could be
