You need to see the logs for the readynas to try and find out what is
going on.
This is what I would do:
Seize the FSMO roles to one of the 4.11.6 DC's
Demote the two 4.12.2 DC's
Remove everything in /usr/local/samba
Test if your readynas now connects to the domain again, try a re-join if not
If you have connection, then good, if not, you need to find out why not
and this will require seeing the readynas logs, you may have to ask
netgear about that.
Once you have connection from the readynas, run 'make install' again
(No, you shouldn't have to totally build Samba again)
Once Samba is installed again, try joining as a DC, hopefully it should
now work.
The only major change between 4.11.x and 4.12.x is that you now need
Python 3.5, perhaps you do not have this ?
