Dear John, > Marcus, I do not think what your trying to do is going to work. Why? > "failover peer "intra-net"" . You will need a dhcp.master configuration file > on both servers. You running two dhcp servers? Debug with only one server. Of course, the failover is set up and working correctly. Please note that I am not new to dhcpd3 configuration. > Her's my opinion.

This behavior occurs on all clients, so I don't think so.
