This has nothing to do with your IPv6 issue ... but:

The broadcastdelay line is only necessary for configurations where a
broadcast client is not able to calculate the delay during the temporary
unicast phase of a broadcast association (e.g. over one way links).

In your case this ntpd is not even configured as a broadcastclient, so
that line has no effect.

Why the "%4" at the end of the address? Can you retry your configuration
without it?

Such testing would require developer access to a Windows XP machine.
