Hello. My dad recently upgraded his laptop from XP to Vista. His vista box can connect to his office's modem router; but at home it's a completely different story.

When I plug in the ethernet cable, it shows that it's connected but websites will not open in internet explorer or firefox.

When i try to diagnose the problem, the error message "Cannot communicate with primary DNS Server (172.40.7.220)" pops out with the option to reset the network adapter "Local Area Connection". But when I click the option to reset, the same error message pops out again.

My Internet Protocal is already set to "Obtain DNS Server address autmotically" and I have no idea what else to do.

Can anyone please help me? ):
