I work at a small company that deals with very sensitive information
and trade secrets. We would like a way to track and log all aol aim
conversations. We are using xp professional. How would be a good way
to accomplish this? The number of people on AIM is 9? We don't want
software that is installed on each client. Rather something that is
able to track all network information from a single computer.

We are even considering something which tracks all internet usage by
computer. This seems to be asking a bit much.

Thanks.

The concrete solution for your problem depends on your network
structure. If you have already a router, you would only need to
install a sniffer on this router and  filter out the traffic on port
5190. Another solution could be a proxy.

There are many product that will let you do this. Spector
(www.spectorsoft.com) is a popular one.It will also let you monitor
all other internet activity.

Maybe something like this:

Search strategy: irc network sniffer record

There are some more products at http://www.spytech-web.com/. Also, I
haven't used it a heck of a lot, but Ethereal is a free network
protocol analyzer (http://www.ethereal.com/).
