Start -> Run -> type "ipconfig /flushdns" (without the quotes) and hit enter.

If you have cable, try restarting your cable modem.

And if you have DSL, try unplugging it, and turning off the modem and router for about a day.

If you have a frying pan, hit yourself over the head and chant:
"..I love you internet!..." Six times.

(If you don't have a frying pan, any cooking pan will suffice)

I heard an iron skillet works even better.

Smack yourself with a spatula until you bleed and then post pictures.

"ipconfig /flushdns"

What does that do? Its' not that I don't trust you, its' just that I remember when Kas tried to help me format my computer.

It flushes the dns information of websites you have visited from your system's cache. Sometimes, the information is 'old' and the system has a hard time reading it. You're actually suppose to do this on a regular basis. Trust me, it won't screw anything up on your computer at all. Best to think of it as an additional way of clearing out a cache most don't know about.
