I sometimes help a small office with a few issues. About two months ago, they were complaining of poor internet performance. Long story short, I found one person running Carbonite on a Mac that was pushing 2mb uploads all day. Shut down Carbonite and the problem -- which I saw as a 2mb consumption in a traffic graphic -- disappeared. I adjusted that user's Carbonite so that it would consume as much bandwidth as it could. (I forget the name of the setting.)
In that case, I went on-site and turned off everything until I found the problem workstation.
I think the problem is occurring again, indeed there is now a 2mb consumption hum in the traffic graph. I'd like to be a lot smarter about figuring out what's happening.
How would you approach identifying the workstation responsible?
(FWIW: Unless something has changed, Carbonite will not release enough information that would allow me to throttling those connections. Search Google and you'll see a whole lotta complainin' about this.)
