I have seen these messages in three instances.  The third may solve your
problem.

1.)  Software issues. The first occurrence is when you have not properly
configured the dhcp client software correctly.  I was a lazy butt and
put my system identification information--in your case the
"cr504xxx-a"--in both the "send host-name" and the "send
dhcp-client-identifier" configuration variables of the
/etc/dhclient.conf file, or lrcfg 3,4,1--"package", "dhclient",
"dhclient daemon config" lrcfg menu items.  One weekend my leaf box
stopped receiving an ip address.  I presume Cox did some weekend work
that broke my miss configured settings. In the case of Phoenix cox@home
service the system identifier should only be placed in the "send
host-name" variable.  I don't recall now but I may have also received
some other dhcp client messages in the system log file.

2.) ISP changes.  After I correctly configured the dhclient daemon, I
had another occurrence when ISP changes broke my leaf box.  I presume
this time Cox was preparing segments of Phoenix cable system to switch
over to Data Over Cable Service Interface Specifications (DOCSIS) cable
networks.  I had a friend that was only a mile away that had to use the
2.0pl5 version of the dhclient.lrp package.  I continued to work fine on
2.0p14 until about two weeks latter when I had to use 2.0p15 package.  I
received another error message from the dhclient package, but it also
gave the same symptoms as you list below.

3.) Media failures.  The cables and connectors in the networking world
are referred to as media or the media link layer.  I live in Arizona. 
The fan on the cpu and power supply filter allot of dust through my
router. Every once in awhile I will open it up and vacuum the thing. 
Tonight I did not push the RJ45 Ethernet connector all the way into the
card.  I booted up and started seeing those same messages listed below. 
I thought humm may be Cox is going the way of Rogers.  After some
futzing about I realized the the cable was secure in the back of the
cable modem but not in the router's Ethernet card.  I pushed and finally
heard the click.  Moreover the link lights on the Ethernet card and the
back of the cable modem sprang to life.   This is a possibility in your
situation, if you have a second Ethernet cable that is secure in the
back of the Windows computer.  You unplug the router from the cable
modem side and then plug in your Windows PC and set the CR number in the
Windows Networking "Computer Name" field.  Everything works great
because of the secure connection.  However, the cable at the router end
is still loose.  So when you plug the router back into the cable modem
you still see the the DHCP messages.  A broken Ethernet cable can cause
the same problem.  LOL and if it wasn't me causing the problem it could
be one of our three cats crawling through the wires while being chased
by one of our two dogs.

I hope this helps,
Greg
