Tell if Win2000 or XP is inactive

[Bart Nessux]

Hello,

Auditors want us to log out a user if the computer they are logged onto 
has been unused/inactive for a set period of time. It's trivial to 
logout the user, but we're having trouble telling if the system is 
indeed inactive. If we could learn that information, then we'd need to 
measure how long it has been like this so we can all the logout 
function. How might this determination and measurement be approached?

We're using Python 2.3.x w/o Mr. Hammonds extra Windows extensions. We 
do not want to install the win32 extensions.

Thanks,
Bart
