[Winpcap-users] using Network Monitor versus WinPCap for real timenetwork usage statistics monitoring/capture?

[Greg Hauptmann]

thanks Gianluca

Any other ideas (noting Q1 answer) re how to monitor/track network usage on
a per PC application/process basis then?   Is it perhaps an unachievable
thing?
