Samba internal DNS client, large replies and TC bit
...P if TC bit is set in answer. There's a real-life
issue with this simplistic DNS implementation.
One of the domains here gained a few more domain controllers. And it turns
out the DNS reply stopped fitting in single UDP packet. So named (9.18.19)
stopped providing replies in UDP answer:

Issues demoting a samba DC.
...s a UUID, also known as a GUID.
Samba has bug for this, it seems that when you demote a DC, its dns GUID
record gets left behind, see:

Computer in Samba 4.3.11 domain - logon server unavailable
...'t report anything useful. We've just seen the IP successfully connecting to port 445, but nothing else.
Could it be a SID problem?
Another error I found in event log is:
NETLOGON 5719: Unable to establish secure connection to a domain controller.

smb.conf:
[global]
name resolve order = lmhosts hosts bcast
