Unsolved problem - finding remote machine desktop locked status

[sat]

Can anyone tell me how to find whether a remote computer running windows
2003/NT /XP has a locked desktop or not ? ( By Locked desktop, I mean the
status where the user presses Ctrl+Alt+Del and locks the computer. ) Is
there any API or command to find this out ?


well the requirement is to find if a person is working on his terminal (
desktop unlocked ) or not (desktop locked)
I do not wish to install any server or client software on his machine. Can
we do this with the already installed products which Microsoft provides (
like terminal server )

I have been looking for its solution from quite some time (close to 6
months - no result ) :-(

Only can check logging status from nbtstat -A [target ip address]. :-(
.... otherwise, use winexit.scr if you wish to force logoff of the user
