Problems with DDNS + Mac OS X as a client

[Jason Lixfeld]

I'm having a hard time figuring out why everything BUT a Mac OS X  
client will work with DDNS.  I have Windows XP Clients, Cisco IP  
Phone, Apple AEBS and Apple AE Clients, my VTech Vonage Phone, my HP  
Printer; everything gets an IP and DDNS assigned, except the Mac.   
I've tried with the wireless and wired interfaces, neither work.  Not  
sure if it's the client, or the server but I think something is off.   
Actually, looking at this again, it appears that coincidentally, it's  
only with dhcpd.conf entries that have fixed-address entries.

Any ideas?

4d = housekat host (wireless) (not shown in this debug, but same  
results as wired)):
