Are you sure you have the "correct" administrator password .. 
 
this should work ,  echo ${SAMBA_NT_ADMIN_PASS}| smbclient //localhost/netlogon -U Administrator -c 'ls'
that does not involve kerberos yet.. 
 
Please run: 
 
SETHOSTNAME=`hostname -s`
SETDNSDOMAIN=`hostname -d`
SETFQDN=`hostname -f`

host -t SRV _ldap._tcp.${SETDNSDOMAIN}. 

host -t SRV _kerberos._udp.${SETDNSDOMAIN}.
  
host -t A ${SETHOSTNAME}.${SETDNSDOMAIN}. 

and 
cat /etc/hosts
 
and these are your DC's ips? 
 
nameserver 75.75.76.76
nameserver 75.75.75.75

 
Greetz,
