I know this looks like some of the other questions but they don't seem to have been answered as fully as I hoped.
On our network we have a bunch of PC's that are connected to the internet. Now for the past few weeks it seems that our downloading bandwidth is being used up. Now we have a very basic tool to monitor inbound and outbound traffic, so that's how I know it is inbound(download) traffic. Now I need to work out what machine(s) is causing this, so far the network monitoring tools either monitor internal network traffic which is crazy anyway and looks like the 'matrix' or it works out total bandwidth used, which is what we have anyway.
I need a tool that can tell me which machine on our network is using the most internet traffic (inbound and outbound) and if not why not?
We have a Windows network. We have unmanaged switches.
