This option will be invoked the first time you configure a
    Phase V node by:

    $ @sys$manager:net$configure

    Choose to continue with this FAST default configuration if:

    -  You are upgrading from a DECnet Phase IV node and you
       plan to use the existing Phase IV configuration.

    -  The node is not in a cluster.

    -  You are not running and do not plan to run this as a DNS
       Server.

    After the FAST configuration has been run once on your system,
    the configuration option defaults to BASIC.  For more
    information about the FAST configuration option, refer to the
    Installation and Basic Configuration manual.
