I'm looking for a program to keep track of how much bandwidth each computer uses on my LAN network. My ISP is starting to charge me for extra internet bandwidth so it would be nice to have some kind of tracking system so I don't go over my limit since I have 3 computers at home it's very hard not go over the limit and get charged insane prices by my ISP. Any help would be appreciate thank you.

I'm not sure of a specific standalone program that can monitor all 3 computer's bandwidth usage...there are several programs that will monitor one network adapters traffic though.

The bandwidth has to be monitored at a choke point, which is the gateway in the typical home network. You can't monitor it from an individual computer, you won't see anything but broadcast traffic from the other computers.
