Getting a PC out of "locked" mode

[guackyxxx]

Help! I had a script that worked perfectly fine until our new security policy went into effect that requires all idle PCs to be automatically "locked" (CTRL-ALT-DEL and then the "Lock Computer" button) after a period of time. Since my script runs unattended at night, but relies on looking for Window title, etc., the fact that the PC locks up and presents the "Computer Locked" window on a blank screen prevents the script from running correctly. The AutoIt documentation says that I cannot simulate a CTRL-ALT-DEL combination to try to unlock the PC before runnign the screen, so I am out of ideas. Any suggestions?

Thank you for the suggestion. Unfortunately, this is a shared PC and I cannot leave a script running (even in the background) all the time.
