[Samba] Problems with Windind Authentication

Hi,

I have a File Server as Domain Member and it was working properly.

Recently I changed my DCs and after I am not getting authenticate users
with winbind.

I'm using Samba 4.6.3 as DC and Samba 4.1.17 as File Server.

When I restart Samba Service, this message appears:

Is it a problem?

There doesn't appear to be anything wrong, so where are not get users
authenticated, on the DC, or on the fileserver, or both ?

Can you post the smb.conf files from both machines.

What OS is this ?
Is there anything like an auth.log on the DC ?
If so, is there anything in it ?
