Any network-dependant applications should be shutdown before
    the network itself is shutdown.

    For a complete system shutdown, the OpenVMS shutdown procedure
    SYS$SYSTEM:SHUTDOWN.COM calls SYS$MANAGER:NET$SHUTDOWN.COM
    before it calls the site-specific SYS$MANAGER:SYSHUTDWN.COM
    procedure.   Therefore, it is not sufficient to shutdown
    site-specific network applications within the SYSHUTDWN
    procedure.

    Instead, the SYS$MANAGER:NET$APPLICATION_SHUTDOWN.TEMPLATE is
    provided for this purpose.  This file should be renamed to
    .COM and edited to include the site-specific shutdown
    procedures of your network applications.  You also need to
    define the NET$APPLICATION_SHUTDOWN logical in
    SYS$MANAGER:NET$LOGICALS.COM to point to this site-specific
    procedure.  If the NET$APPLICATION_SHUTDOWN logical is defined,
    NET$SHUTDOWN will call your site-specific procedure to shut
    down the network applications before DECnet itself is shut
    down.

    To shut down DECnet-Plus, enter:

    $ @sys$startup:net$shutdown

    To restart DECnet, enter:

    $ @sys$startup:net$startup
