You really should run "testparm -sv 2>&1|less" and resolve any errors

The code is doing what it can to let you know there are problems with
the basic configuration file, and possibly the installation.

There are 2 DC's being found, but the connection is being refused like
I thought (until samba4) that domain controller policy had to allow
anonymous connections, but I've found a messages that suggest this just
masks an underlying problem.
Security settings/local policy/security options/
Allow anonymous SID/Name translation (enabled)
Do not allow anonymous enumeration of SAM accounts (disabled)
Do not allow anonymous enumeration of SAM accounts
and shares (disabled)
See how they're set and maybe experiment with one or more settings.
Make sure the domain join is OK.
Try and fix the config files (obsolete & unknown values) and
installation (missing objects). Over the years I've learned errors in
the config can have unpredictable impacts on performance. Start
troubleshooting with a clean slate.
