Situation: Trying to upgrade Samba from 4.1 to 4.5 without disruption
too much by adding new DCs and demoting old ones.
After bringing online the first 4.5 DC, I ran `demote

At that point, some (but not all) of our file servers started throwing
NT_STATUS_NO_LOGON_SERVERS (smbd) and
NT_STATUS_DOMAIN_CONTROLLER_NOT_FOUND (winbind -P). Windows' RSAT tools
also completely fail to connect to the domain.
Some of the old DCs started throwing "Failed to bind to uuid

Attempts to remove the new ADDC fail with "(2, 'WERR_BADFILE')".
So… How the fuck do I recover from this? What's even wrong?
