Was your old domain server an NT-4 style PDC ? you didn't use kerberos 
with this type of server. Now that you are using a Samba4 AD DC, you 
have to use 'security = ADS' and keytabs, the main keytab (usually 
/etc/krb5.keytab) is created for you when you run 'net ads join -U 
Administrator', the join should create the dns record for the client but 
sometimes it doesn't. This is not a problem, you just have to create 
them manually on the DC with 'samba-tool dns add <server> <zone> <name> 
<A|AAAA|PTR|CNAME|NS|MX|SRV|TXT> <data>'. See samba-tool dns add --help' 
for more info.

Having said all that, one thing that I don't think has been raised yet, 
how did you install samba on the DC ?
