Hi Kyle, I suggest looking in /var/log/messages (I believe the default confiuration for CENTOS logs everything into there )
You should see lines like: Feb 15 06:25:34 vampire dhcpd: DHCPREQUEST for A.B.C.D from some:mac:address:here via eth0 then you might see something like Feb 15 06:25:35 vampire named[3921]: client 127.0.0.1#53: update 'keg.ertos.in.nicta.com.au/IN' denied or, Feb 14 17:35:04 vampire named[4854]: client 127.0.0.1#42217: updating zone 'keg.ertos.in.nicta.com.au/IN': update unsuccessful: bigmac.keg.ertos.in.nicta.com.au: 'name not in use' prerequisite not satisfied (YXDOMAIN) You may also want to check that can update named manually, using nsupdate. As root, on the machine running dhcpd, do nsupdate -k keyfile server whateveryournameserveris domain domain.com update add fred.domain.com 864000 A 192.168.1.100 show send or similar. Then try host fred.domain.com to see if you can see the record you just added.
