{ Q: We're forcing our users to change their passwords every 40 days.
     After the password expiration date, they have 3 grace logins, one
     of which they should use to change their password. To force them
     to change their passwords whenever they login after the expiration
     date, we need an utility that returns a distinctive Errorlevel
     whenever the password has expired.

  The following program will return an errorlevel 0 whenever the calling
  station's password has expired (current date later than expiration
  date). In all other cases (i.e. an expiration date wasn't set, 1 will
  be returned.
