Specifies that a logical port on your local node is limited to
    a service in the same way a port created using the /DEDICATED
    qualifier is dedicated to an application service. The difference
    is that ports created using the /LIMITED qualifier are under the
    control of the system login image (LOGINOUT.EXE) instead of an
    application program (a user who connects to a limited service and
    is assigned to a limited port receives the "Username:" prompt).

    Using the /LIMITED qualifier, you can create a limited number
    of ports and map them to a specific service offered by the host
    system. If users are logged in to all of the limited ports for
    the service, no more connections are allowed to that service
    (terminal server users receive a "service in use" message).
