For some reason there are a few things I can't do on this internet connection I'm on right now. Everything works fine on the host computer, it is just a few things that won't go. So far I have only had problems with Hotmail (separate client AND website won't connect). Myspace and Cnet. I can run skype and yahoo mail, though, which is weird.

Does anybody know of anything special that these three things share in common?

EDIT: Windows updates won't work either...
