The user "Jeff" wrote "IPv6 is on in Vista by default-you can turn it off though.
--Go here,
--Control Panel\Network and Internet\Network Connections
--right click your network card>properties
--uncheck the IPv6 box

that'll turn off IPv6-then just disable the adapter driver

That's if it's causing you issues,".

In my case, the wired adapter card (ethernet) was unchecked for IPv6. I needed to uncheck the wireless card for IPv6.

User forums show Microsoft has disabled support in Vista for this IPv6. It is the new standard for internet names of website.
