A protocol analyzer is a program like Ethereal (http://www.ethereal.com) or
Analyzer (http://analyzer.polito.it/) that captures network traffic and can
show you, usually graphically, who is doing what.
IE, which computers are generating traffic to/from on specific ports (like
Kazaa or a spam engine) or computers constantly connected to a specific IP
address with a specific protocol (AIM, iRC, or maybe Internet Radio) etc...
Normally this program would be installed on a machine between the border
server and the internet. In the DMZ, so to speak.
I use my laptop. I set it with a static IP in the DMZ, plug it into the DMZ
hub, and start grabbing packets. In a few minutes, I have a good handle on
what is eating bandwidth.

Glenn,
I have no idea what a protocol analyzer is, and I am certain no one else
here does, either. (Although I am sure you are correct, that this would
help.)
What is Kazaa? And how do I determine if anyone is running it?
