    Could be all sorts of things. It could be a virus/trojan for example.

    You might want to look at netstat to get an idea of what is sending these. Sysinternals do a nice applet that gives more details of what is talking.

    Can you tell us why you think it is broadcasting?

    That would have been one of my questions also. :)

    One way of finding out what's going on is to use Network Monitor. Capture some traffic then analyse it and see if anything unusual is happening. There is a guide available which will show you how to install and use it on Win2K.

    You may also want to consider using the performance monitoring tools built into Win2k Server as they will give a huge amount of information about your network card and how it's operating. The bytes sent / received status that you showed in your pic really is far too little information to base any conclusions on.

    The guys from Packeteer showed me a new software app that they've brought out that can monitor traffic from a machine and identify the traffic at the layer 7 level...but obviously it needs to have a particular traffic signature in it's definitions library. It was that good that I cannot recall the name??? Is that age? lol

    That is a lot of packets in 52 minutes.

    What is this server serving, streamimg media?

    How many local clients are connected?

    Do the sent packets drop if you disconnect from the Internet?

    Do you have P2P software on it, limewire etc?

    Are you inadvertently hosting a warez site?
