What exactly do you mean by "doesn't start"?

Just to ask, what does your ntp.conf file look like?

I suspect a DNS problem on your machine.

Assuming your machine gets low enough traffic, I have found that when I
start ntpd with debugging I can watch the ntpq or ntpdc packets arrive and
the responses get sent back.
