In the "old" domain we had severe issues if WINS was not enabled. And
as we have a "grown" environment with NT, XP, Mac, Win7 and Win2003/8
we did not risk it to switch the old WINS server off. So what you are
saying is "wins support = yes" only works on domain members correct?
That is the way it is running now. I just thought to use the DCs to
have some kind of failover.

Here the relevant part from the conf.

failover peer "dhcp-failover" {
        primary; # declare this to be
the primary server
        port 647;
 peer address;
        peer port 647;
delay 30;
        max-unacked-updates 10;
        load balance max
seconds 3;
        mclt 1800;
        split 255;

as you can see only one server is actively handing out IPs but both try
to update the DNS entries. The dynDNS was done as per the WIKI
