How long are the packets?  Both the ones that work and the ones
that don't work.

NTP has some optional authentication stuff that gets appended to
the standard packet.  There is some discussion on another list
about MS inventing their own incompatible authentication.

If the packets that don't work are longer than normal, that's
probably what is going on.
