Tony,
	Why are using HA?  If you have a cluster already running and just want
to put dhcp on the two servers you can do that.  Just create two virtual
ip's and put one real server in each vip pool.  Then run dhcp failover.
 Note:  This will only work if your forwarding dhcp requests using udp
port 67.  I'm not sure how well it will work with broadcasts, if at all.
