A client has a SBS 2008 server on a small network with two other pc's (most of the guys work remotely). They have been reaching their 50gb monthly bandwidth by half way through - for the last 4 years they never reached their bandwidth. I had a quick process of elimination and watched the stats on their router and mb's downloaded when i unplugged the newtork cable for the server. It stabilised. When i plugged it back in again the bandwidth started getting hammered again. I'd like some recommendations for tools to install so that i can get some visibility on what is being downloaded. I had a look at wireshark but digesting the information in this context is challenging. I essentially want to find out what is being downloaded and by what service or program. I used netstat but can't see how much mb's each process is responsible for downloading.
