Please post your dhcp configuration, especially the bit where "failover
peer" is defined for both servers (as it should be different). Post the
startup messages that get wrtten out to the terminal when dhcpd starts
on each server. The mailing list software does not accept attachemnts
so paste it in the body of the email.

The rest here is a guess, but things to check:

The time on the two servers is pretty close. Best bet i sto use NTP to
synchronise the clocks accurately.

That you can ping the other server. If there is a firewall in between
check that communication is allowed on the ports specified in the
failover peer definition.

You do not need to put anything special in dhcpd.leases. In fact for a
new server this should be a zero length file. dhcpd will write the
status information once it connects to its peer.
