How to auto lock pc when being idle for a period of time

[nhung t]

Users in my XP network sometime walk away form their
desks but forget to lock their PCs up (they knew better,
but it still didn't click!).

For security concerns, I want to config so that their PCs
will be auto locked for a preset idle-time period. If
anyone knows how, please guide me. Thanks for your help!

You can configure Group Policy to enable the password protected screen saver. Just be
sure to block access to the screensaver tab so that employees can not override it. I
believe it is in user configuration/admin templ/control panel/display. --- Steve

I can recommend you DMVsoft solution for this purposes. I'm talking
about ActiveScreenLock. This program simply adds a password-protected
window placed on top of all the others. In order to remove it, a
correct password needs to be entered. Key combinations Alt+F4,
Ctrl+Alt+Del, Alt+Tab, and WinKey are blocked.

The blocking window can be activated by clicking program's icon or
AFTER computer being IDLE for a set period of time. I'm sure, that
this is what you're looking for

It has one more advantage over a standard windows' locking function:
you can monitor all of the running application, adjusting the windows'
transparency. This program is easily launched with one click.
