Your DC appears to have two ipaddress's :

Jul 21 23:49:14 dc-cloud named[637]: listening on IPv4 interface eth0, 
75.119.155.151#53
Jul 21 23:49:14 dc-cloud named[637]: listening on IPv4 interface eth1, 
192.168.8.1#53

Yet the failing reversezone doesn't match either:

Jul 21 23:49:14 dc-cloud named[637]: zone 1.168.192.in-addr.arpa/NONE: 
has no NS records

It might be a good idea to post your smb.conf and named conf files.
