Occasionally you need to restart the portmapper too, which you do by
killing the nfs daemons as above, running
/usr/sbin/pmap_dump > /root/table.tmp
killall portmap (or rpc.portmap or rpc.portmapper or whatever your system
calls it)
/sbin/portmap or /usr/sbin/portmapper, or whatever.
/usr/sbin/pmap_set < /root/table.tmp
rm -f /root/table.tmp

9 out of 10 times when I get this error I've not configured the
hosts_access(5) files for portmap (which needs it's own special entry, as
per portmapper.txt that comes with the distribution -
/usr/doc/netbase/portmapper.txt.gz on debian)
