problems removing NFS mounted filesystem

Question:

Customer edited a mounted filesystem out of /etc/filesystems, and has
turned off NFS on the machine that exported the filesystem.  Now he
repeatedly gets a message on the 6000, "clnttcp_create rpc:program not
registered  rpc: statd cannot talk to statd at \"

Response:

 A:    This message is caused when the client machine cannot contact
    the statd daemon at the server.
       In effect, your server has a "prior knowledge" of the machine named
    "jeff" ( and other connections as well) which need to be removed to
    stop the transmission of the error messages.
        This can be corrected by entering the following:
     stopsrc -g nfs
     stopsrc -s portmap
     rm -r /etc/sm
     rm -r /etc/sm.bak
     rm /etc/state
     rm /etc/xtab
     rm /etc/rmtab 
     startsrc -s portmap
     startsrc -g nfs
     exportfs -av
     
     NOTE:  The order the operations above is important.  The statd
            and lockd daemons must be stopped before removing the
            files and directories.
       The status monitor maintains information on the location of
    connections as well as the status connections in /etc/sm, /etc/sm.bak
    and the /etc/state files.  When restarted, the statd daemon queries
    these files and tries to reestablish the connections it had prior
    to termination.  The steps outlined above will recycle the statd and
    lockd daemon, without prior knowledge of existing locks or status,
    by stopping the daemons, and removing /etc/sm, /etc/sm.bak, and
    /etc/state, then restarting the daemons.
