First thing you'll want to do is evaluate your existing hardware and software to know exactly what you have for resources.

Second, you'll want to have your network configuration well documented.

* If you are running managed switches, the built-in web interface should offer tools to help you identify  at least the physical port generating the traffic.  Using your network documentation, you can determine where that physical port is, and address that particular machine.  Depending on the switch, you may even be able to disable that port.

*  Consider implementing a solution using MRTG or PRTG for monitoring your equipment as well.  both are powerful tools and allow traffic graphing of SNMP-enabled devices.

* Use network sniffing tools like Wireshark, EtherReal, etc. to monitor traffic.
