After you've checked to make sure you're not infected with some kind of worm, take a look at this:

What app tends to cause the problem?  P2P?

The half open limit is very small near 10 or 50 - for things like Bittorrent you need well beyond that.


There is a TCP open connection limit patch available out on the net. It was first created for XP but now they have one for Vista. It will solve you issues with Bitorrent.

I would link it for you but my corp firewall won't let me. Search for 'TCP half open limit Vista Patch'
