[Samba] NETLOGON failure

[Viktor Trojanovic]

Hi list,

Checking the Windows event logs, I see that my clients regularly
complain a netlogon failure:

Event 5719, NETLOGON
This computer was not able to set up a secure session with a domain
controller in domain SAMDOM due to the following:
There are currently no logon servers available to service the logon request.
This may lead to authentication problems. Make sure that this computer
is connected to the network. If the problem persists, please contact
your domain administrator.

Unless I'm missing something, this message doesn't seem to have any
impact on me as all seems to work as expected (DNS, NTP, GPO etc).
Also, there are no logs whatsoever with regards to this error on the
DC.

Do others of you face a similar error message? Is this something that
can safely be ignored?

My config: Samba 4.3.1, Standard single AD DC config as per Samba
wiki, internal DNS, Win10 clients
