Internet usage and monitoring

["Jon Petre" <jono-31 () hotmail co uk>]

Hello List,

I am looking for an idea/program to monitor users internet usage. Due to the 
nature of the customer who requires the monitoring carried out, this program 
must be able to run on a windows box and needs to be very reasonably priced 
(I have no control over budget unfortunately). I am aware of programs such 
as ISA server (too expensive) and squid (*nix based). Any other sugesstions 
would be great.Customers network is round a bout 20 workstations that need 
to be monitored, so pretty small in reality.

Looking forward to all your help.

TIA

Jono
