I have a LAN which has about forty wired clients and a few wireless clients connecting to a server running Server 2012. All clients can connect either wirelessly or wired, depending on whether or not there is a convenient network port within two metres. The setup is as follows. Phone line comes in to DSL router, this then plugs in to NIC#1 on the server. Line runs from NIC#2 to switch which then branches out to two other switches (and from there, wall sockets) and WAP.

#---DSL Router---(NIC#1)Server(NIC#2)---SWITCH1---SWITCH2---SWITCH3---WAP

Every user/machine is authenticated by Active Directory and users do not have software install privileges (although they can bypass it in VMs if they have the tech knowhow I suppose). I want to know how I can monitor the bandwidth on each client/user as my boss is complaining that his IT provider is giving him grief for exceeding their 'fair usage' policy. Not sure what is sucking all that data, WireShark hasn't been much help in IDing any rogue programs as yet, but I'm sure If I can tie it down to a single PC (or two), I can investigate further.
This will need to be achieved by running software on the Server 2012 machine. Any ideas?
Thanks Mark
