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).
