Any help anyone could provide me would be appreciated

winlogon /desktop switch
-winvnc need to be running as service
-viewer need to have autoreconnect enabled ( set to value like 3)

Cause:
Vista>= use different sessions for winlogon/desktop
sessions are isolated
winvnc need to be running in the active session

The winvnc service, monitor winvnc and restart winvnc in the active session.
Restart -> connection with viewer breaks
autoreconnect viewer-> viewer stay open and reconnect in background
