NEtwork Traffic

[netadmin06]

Hello to all I have a network with a Windows 2003 Server Domain Controller and 50 client workstations. I want to find out which of my clients is eating up all the bandwidth..is there an easy way to tell which client is using most of the bandwidth?? ( internet bandwidth )....i just want to find out so that I can tell the user to stop using whatever application he is using that is taking most of the bandwidth and slowing everyone else's internet connection

PD I have admin rights to all servers and clients

to what kind of hub/switch are your computers connected?
cisco switches have a feature that lets you monitor a port.
when you monitor a port, the switch send a copy of every packet on on the source (monitored) port to the destination (monitoring) port. then, one can use a tool like wireshark to see what computer is using all the bandwidth.
in your case, you monitor the port on your switch to which your internet router connects

if you don't have a switch that supports monitor, you can put a hub in line on your internet connection, connect a PC running wireshark to that hub. a hub allows you to see all packets that the ports to which is connected see

All Clients and servers are attached to a Lynksys switch (srw2048)..the switch has a cable that goes to the Cisco router...

That switch supports port mirroring.
You may alow be able to use the web interface on the switch to see what ports are sending/receiving the most traffic.
Go to linksys.com and look at the documentation for that switch.

It appears that this switch supports SNMP. If you get a copy of Nagios (you may want to try the VMWare Appliance that can be run on Windows with the VMWare Player), I believe that you can monitor usage in a nice graphical web interface.

Just a thought, rather than going through and monitoring yourself, you could set up a box that monitors and distributes the bandwidth like NetEqualizer. I've had one that monitors over 100 clients for a few months, and everything seems to be running smoothly. Give it a try maybe.
