This response from the helper is clear:

There is an NTLM authentication request without domain, but the
domain field is mandatory for NTLM authentication with the current
ntlm-auth.exe helper.

Some of your client is sending user credentials without domain, may
be local users or a machine not member of the Windows domain.
