Please tell me that you haven't turned your Windows DC back on again. If
you have, is it connected to the domain ?
If it is, then turn it off again and never turn it on again whilst it is
connected to the domain.
If everything is working correctly on your Samba DCs, once the Windows
DC is disconnected, run:
samba-tool domain demote --remove-other-dead-server=<THE_WINDOWS_DC>
on one of the Samba DCs
I would then take the Windows DC outside the domain (so it cannot
connect) and then reinstall an OS on it, this will stop you ever
bringing the Windows DC back again.
