As I understand it, you have a Samba AD DC that is running correctly, 
but cannot join another Samba DC to the domain.

I can think of two things to try (both using a new DC name)

use '--server=THE_EXISTING_SAMBA_AD_DC' with the join command


Turn off the Windows DC whilst you attempt the join, this will force it 
to use the existing Samba AD DC during the join, though you will have to 
ensure the existing Samba AD DC holds all the FSMO roles.
