Slow to no internet after Vista Updates

> I hope you guys can help me. I've been running Vista Ultimate x64 since

> What's happening is this. Anything that needs DNS resolution on the
> internet resolves very slowly then a few seconds to minutes later it
> takes soo long to resolve names that applications requesting the
> resolution time out. So email times out. Webpages time out. My antivirus
> can't pull down its updates. Torrent downloads work fine. Chat programs
> work fine. I have a LAN. Both of my XP laptops are still able to work
> normally on the internet. I thought maybe it was my FiOS router so I
> reassigned the IP addresses for my computers. No change. I can reboot
> the Vista box and get connectivity for a short time. The time varies.
> Simetimes it's only a few minutes and other times it's over an hour. I
> installed SP1 hoping it would resolve this but no luck. I can access
> file shares on my other machines from my Vista box w/o any issue. My
> loptops have no issues streaming A/V from my Vista box. This is driving
> me crazy.
