I have 3 PCs running Windows(including my PC) on the same network. All three of them are connected to one ADSL Router. My requirement is to measure the internet usage(No. of Bytes Downloaded & Upload) by other two computers on the network. Also I don't have access to other two computers and therefore I can't install any Usage Monitoring Software on those two PCs.
Taking the above facts into consideration is there any way I could monitor Internet Usage on the network?
Thanks!
