Windows Vista Network Connection Crash

[g4hsean]

Hi I just installed windows vista and noticed a couple of problems, whenever I'm on the Internet and I'm trying to download something the connection seems crash. It only seems to crash when I use Azureus or some kind of downloading program. I notice that it crashes when I also use windows messenger, does anyone else have the same problem?

P.S does anyone have any information on how to fix this problem? Some it loose thread
