I'm not sure I understand what you are showing us. You appear to be
shutting down ntpd running ntpdate and then starting ntpd again. Why
exactly are you doing that and what are you expecting to do thereby? It
is not clear why you are running ntpd v 4.1.2, you need to upgrade. It
is also not clear from this what servers ntpd preferred in getting it's
packets. Do you know that it was the same as 172.17.2.71? If not do you
know the difference between them? Is it in your ntp configuration file?
