Looking for a free/low cost utility/app so we can monitor and tell where all of our network bandwidth is going. A few times in the past month, all of a sudden we will get a broadcast storm, but am unable to identify which client pc is causing this. So we need software that can do the following: 1. Show each connected clients bandwidth in real time, who’s using the most of the network bandwidth, etc…. 2. Show external traffic from outside of our network to each client/ or server. Showing inbound packets, from the source to destination client machine. If you can recommend a good program, would greatly appreciate it. Thanks!

Did you try searching this on google before coming here? A quick search of "network monitoring tools" will give you enough hits to keep you busy reading for a while. I know, I went there and searched that exact string myself recently.

Yep, spent 30+ minutes on google, wading through everything. I have no idea which one is useful, or not? If any network admin is using a app they are satisfied with, give a heads up. Thanks!

ethereal is a good network tool. and its free too. www.ethereal.com
