Who's eatting all my [internal] bandwidth?

I'm trying to find out what's chewing up all my internal bandwidth the my server. I've got overall network monitors to show how much of my server's bandwidth is being used but I'd like to find out who (and/or which processes) are hitting the server.

Knowing that my utilization is at 30% is great and all, but I wan't to know WHO is responsible for the eatting my bandwidth.

Is there a free tool that will show me this sort of information?

Thanks!

I should have added, after you run Wireshark's packet capture for a few minutes (Capture > Interfaces). The first items on the Summary menu will give you the high level information you're looking for. If you need more granular details you'll want to read up a little on Wireshark filters. I've also found merely sorting by various columns in Wireshark can be very helpful.

Thanks ryansoto, glebn, and Johnjces.

The information is very helpful. I had considered WireShark but didn't look into it much, but due to the high recommendadtion, I'll give it a shot. Also, I didn't know about the MS Network Monitor. Thanks all.

I thought I would jump onto this discussion as a beginner in the realm of network bandwidth analysis. I manage a SBS 2003 / XP Pro office with 25 users. They share a common internet gateway/router (NetGear) running about 1 Mb up and down. Intermittently, throughout the day, their internet access (desktop people accessing the internet through IE) slows to a crawl for anywhere from 1-15 minutes and then recovers. They don't use IIS on the server for any outside access. How do I see what is happening on the entire network and capture which IP addresses are grabbing the greatest bandwidth during those slow-down events? Do I need to install something on each computer and then monitor it using software on 1 computer? I installed WireShark but it appears it just monitor traffic on that computer.
