How to deal with open ports?
This is not a specific case or emergency.
I would like to know how to close open ports, who has opened those ports and information about why those ports are open.
I know I have no trojans, virus, etc... but sometimes I find some open ports that I dont know which program did it.
Right now I've the 8086 port opened, and I still cant figure out why.
Is there any software, registry stuff or somewhere to check about all this, and close those ports?
I know everybody fix this kind of problem telling about to install a firewall, but I still feel curious about what my computer is doing and why.
Thanx.

It is hard to really find out why, no matter how experienced you are, or points that you have.
A point of clarification: ZoneAlarm does not just close port. It is a door, not a wall. So when a product tries to use a port, the first thing to do is make sure ZA not only tells you, but prompts you for permission. Such as, do you want to let Internet Explorer access the Experts-Exchange? (say 'yes', you like us)
So it does give you more information and control than a freeware would need to.
