After all this, with all due respect I wonder how much testing of this functionality has gone on with Windows XP? I have low confidence at this point that the prefix-matching mechanism in ntpd/ ntp_io.c:findlocalinterface() is working well for XP, at least for link-local addresses. I would be glad to have someone contradict me, or to point out my error in configuration. I would also be glad to add a bug to the bug list if that's appropriate.
