I don't think you can - easily.

Firstly, the ISC server can only update to one server. However there are ways round \
that using common techniques (shared virtual address, load balancer, etc) in the HA \
world which aren't related to DHCP.

Secondly you need a DNS ssytem that can handle distributed updates. BIND doesn't, I \
don't know if MS does with it's AD stuff.

Bear in mind that if a DDNS update fails, the DHCP server will retry it every time \
the lease is renewed until it's accepted. So it's probably not the end of the world \
if DNS updates don't happen for a short time. On that basis, I;d suggest you would be \
better putting your efforts into making your DNS infrastructure itself fairly \
reliable and having plans for how to deal with failures. \
