Unlock event not found after RemoteDisconnect in Windows application - SystemEvents

event

I have an application that listens to system events using Microsoft.Win32.SystemEvents. But for some reason, after connecting to the machine with a Remote Desktop Connection and disconnecting it, the next time when I actually or locally unlock the computer I don't receive a SessionUnlock event.

Could someone help me understand why and what could I actually do for this. I have tried locking the machine first using

"public static extern void LockWorkStation();"

, but that does not work.

Any solutions?? or any other events that can detect RemoteDisconnect or LogOn???
