Two things.  First rather than modifing the ntp entry in /etc/services
you should add an additional entry identical to the first except for
udp
instead of tcp.  Second if you are running YP you will need to modify
the yp data for services and do a cd /var/yp;make services.

I assume you know about running tickadj -Asq before starting xntpd on a
sun.
