You're not the first person to report this.  There's been numerous
reports of it here on freebsd-ports, and it's always between ISC dhcpd
3.0.4 and Windows machines.  This time around, however, I really don't
think Windows is to blame (especially since 3.0.3 works).

I've yet to see anything about what the actual cause is (is it a
FreeBSD port problem, or is it something in ISC's dhcpd which got
changed?).

I haven't upgraded to 3.0.4 on my LAN, and to be quite honest, I
doubt I'm going to until this can be tracked down and solved.
