The best is

	service ypbind restart
or

	/etc/rc.d/init.d/ypbind restart

The problem is that if you kill the ypbind process and restart it, you
leave the old maps in /var/yp/binding.  ypbind won't overwrite them, so
you still have the old mappings.  The above commands stop ypbind, delete
the offending maps, then restarts ypbind.  ypbind then rebuilds the maps
with the correct data based on your new config.
