Share an NFS share via Samba has never worked reliably.

I take it you missed all the warnings about not using a Samba DC as a
fileserver.

Guest access on a DC ?

You should remove the line above.

You shouldn't attempt to use a share on a DC as if it was a share on a
Samba Unix domain member, see here:

You must follow that for any chance of getting things working correctly.
