Hey David,
If you simply want to find out which users are the main offenders then
running NetFlow is a good idea. This will tell you the top talkers / ports.
Here is a link for ntop: http://www.openxtra.co.uk/products/ntop-xtra.htm it
is free. This will create some cool reports you can modify for management
as well.
If you want to know exactly how much bandwidth you all need for a specific
application, and QoS target, then I recommend visiting www.corvil.com and
check out what they can do for your QoS design and provisioning.
Throwing bandwidth at a problem is not the answer... Engineering and
provisioning your network should not be guesswork (even educated guesswork)!
Kindest Regards David and happy holidays,
Andrew

Subject: OT: PC Bandwidth Usage Check
Hi guys
We've a bit of headache. We've got a office LAN in a business centre where
the
Internet access bandwidth is charged per usage. We have slots where e.g. for
up to 4 GB upload/download the cost per month is X amount. If we exceed this
limit then each extra GB etc is charged at a higher penalty rate (more
expensive then the agreed/contracted rate of 4 GB per month at cost of X).
We've modified the contract to have 10GB per month contract at a higher
cost.
We are still getting the access usage of the Internet bandwidth. We want to
see which users are causing this extra Internet traffic. There is no
business
case for downloads/uploads for more than 10 GB per month. So we must trace
the
user(s) and make sure that the stop downloading whatever is casuseing this
extra cost. There are only 6 people in this office. Can anyone recommend any
tools? Prefereablly not too costly (free would be best :D).
Thanks a lot
David
