Internet usage monitoring for domain computers
I have a small SBS 2011 Domain with 2 servers and 5 work stations. My daily internet usage has jumped from less than a gigabyte to about 3 - 5 Gigabyte per day. Is there any software availble to record internet usage per computer (not per user) with detailed info of destinations.
This depends on your budget and existing infrastructure. If you are using a firewall such as a PIX or ASA you can use Fireplotter (http://www.fireplotter.com/) to record statistics.

This solution is only available to members.

To record usage, you wither need to be in the path of traffic, or have another method of recording all traffic.
If you have an unused pc or laptop in combination with either a managed switch on which you can setup a monitor/span port, or a hub (not a switch) that you can place between your existing switch and your firewall, you could install Linux and ntop http://www.ntop.org/overview.html ntop will also work with NetFlow and sflow if you have either available on your switch or firewall.
