This means your failover server transmitted an update for a lease
that was in the ACTIVE, EXPIRED, or RELEASED states, and did not
contain a chaddr option.

I'm guessing you wrote out a new dhcpd.leases based upon your Win2k
server's status, and...wrote out client identifiers and no 'hardware
ethernet' lines in the lease {} stanzas?

I dunno, but you know where to look.

BNDUPD is a failover protocol message.  "Binding Update".
