what is the best and most popular software to track a users every move
on the copmuter, which programs and documents they opened, web sites,
how long they stayed, if they burned a CD or sent email, etc.  I want
to have a record of everything an employee does on the computer, every
mouse click.  Also, is this even possible using somehting the
operating system itself in W2K Pro preferences?

http://www.soft32.com/download_122708.html is a pretty good one. The
link to to a free trial Version the full version will cost around 70
bucks.

 Elite Keylogger is the best selling surveillance software for

activity, clipboard and more. Elite Keylogger is your only complete
privacy fortress that will protect your PC and inform you about every
keystroke made!

Elite Keylogger provides the equivalent of a digital surveillance
history so that you can see exactly what your family members,
neighbours, employees or other users are doing on the computer. Elite
Keylogger works absolutely secretly saving all the recordings in a
hidden location only you know about, all the logs are encrypted and
cannot be viewed by anyone but you.

And then use this so they will most likely not know that its on the
system http://www.soft32.com/download_65514.html

tried Elite Keylogger, after installation and reboot desktop was not
visible, could not use keyboard, mouse was visible but nothing to
click.  had to remove program in Safe mode to get access to my
computer.  Amazing how programs like this ever get anywhere, and this
was supposedly the best one, others i tried were even more useless,
would not install at all.  Who recomended this?  Did they use it or
are they selling?  This service should be called "Guesses", not
"Answers".
