If the connection leaving the computer is via an Ethernet card, it is probably possible to capture the data packets with a "sniffer" tool. Ethereal is the popular free/open source choice; you may find the latest versions under the name "WireShark". If you can capture a few seconds worth of this traffic and send me the packet file, I have additional analysis tools that may shed some light.
