Forcing start order of init scripts

Dear List, I use NIS to distribute /etc/hosts for lan hostname lookup. This works fine for all but one machine. For some reason, ypbind is not running on that machine until after xntpd tries to resolve my gateway's hostname to get initial time sync. Can I force /etc/init.d/xntpd to wait until ypbind is running? How? Cheers Dylan -- "The man who strikes first admits that his ideas have given out." (Chinese Proverb)
