dont know if you figured it out yet. i just installed windows 7 ultimate 64-bit 2 days ago and have been pulling my hair out over the same issue. everything seems to be configured correctly, right? i ended up staring at my network adapter setting for some time and realized the rest of my computers are not using TCP/IPv6, everything else is using v4.
