unlock a computer by DOS command


I run some codes on an NT machine. At the end of the code I inserted a system command "logoff" so that when the code execution is completed, the computer automatically logs off. However this only works if the computer is unlocked. When the computer is locked, "logoff" command that is embedded in my code does not work. I was wondering if there is any DOS command that I can embed in my code, so that when the code execution ends, first the computer gets unlocked and then I can call "logoff" command. Thanks.

try to disable the screen saver and run your code again with logoff at the end.

this is one solution yes but, for security reasons i need my computer be locked when i am not there.

you can manually lock your workstation. what i meant was that you need to disable the screen saver for properly calling LOGOFF command.
Here you go - straight from Microsoft themselves (a script to do what you need):
