Not so fast there... I think nslookup will still default to searching
for an A record, but I'm pretty sure that ping will first look for an
AAAA record under Vista and above.

Try doing 'ping -4 www.microsoft.com' and see if that makes a
difference. I certainly get 'Ping request could not find host
www.microsoft.com. Please check the name and try again.' When I try ping
-6, although the default behaviour _should- be to try ipv6 and then fall
back to ipv4...

If that works, and you really don't use ipv6 for all, disable it as a
protocol on the network adapter. Maybe you already did this before but
then installed gplpv which installs a new adapter and has ipv6 enabled
again? Or maybe you want to use ipv6 and for some reason it doesn't work
with gplpv... I haven't tested that very much.
