I need to have the windows screen saver activate with a login screen after 10 minutes on Windows XP SP2. I know how to go in the display settings and set the sceen saver to 10 minutes and on resume use password. This has proven to be unreliable on this machine. We set it to 10 minutes and walk away for 30 and come back and we still see the desktop. Is there a more reliable way to have the machine lock itself after a period of inactivity?
I am assigning a lot of points as this is important to me.
