Humph, that's expected if a client asks for the wrong network.  It looks 
like your new device thinks it has a valid lease somewhere.  When it asks 
for it answers the ping packet check from the server which should send a 
DHCPNAK to get the client to abandon the wrong network it has and ask 
again via a new DISCOVER request.  The authoritative statement just allows 
the server send the DHCPNAKs.  See the dhcpd.conf man page for a more 
exhaustive explanation.
