On the grounds that paranoia is clearly better, my suggestion at this point=
=20
would be to run tcpdump between the caching resolver and ntpd and see what =
is=20
actually going on the wire.  The name server should be rotating them in rep=
ly,=20
and it would be good to confirm that it's doing that.  It would also be goo=
d=20
to check that it's looking up what you think it's looking up, and indeed, w=
hat=20
it should be looking at.
