Your main problem appears to be that you have a lot of duplicate objects 
in the DNSDOMAIN context, these are the records with '0ACNF' in them.

Have you stopped your Windows clients from updating their own records ?

As you are using dhcp, I would delete all those records (they will get 
recreated if required), then run on the DC with the PDC Emulator FSMO role:

samba-tool drs replicate <destinationDC> <sourceDC>
