"Do you want to convert the Phase IV node name database?"

    If you answer YES to this question, the NET$CONFIGURE procedure
    uses the system's existing Phase IV node name database to generate
    a local name database.  This file is used to translate node names
    if you include "LOCAL" in the list of directory services to be used
    on this system.

    This will provide a flat naming space that is populated with the node
    names from the existing Phase IV permanent database.  This is
    unnecessary if you do not intend to include "LOCAL" in the list of
    directory services to be used on this system.
