If you have no trusts in your organisations, then you should not see this. Check the domain DCs that a trust has not been left after disconnecting from another domain and that none of the PC users are still logging into a cached domain user from a disconnected domain.

It could also be an external user connecting to your LAN instead of your public WiFi maybe..

Is it alongside an event 5719?

If so it is probably a sign that the domain controllers were unavailable or restarting or similar, and the server couldn't find the domain the PC was addressing.

Event ID: 5719
Task Category: None
Level: Error
Keywords: Classic
User: N/A

Description:
This computer was not able to set up a secure session with a domain controller in domain smithFIELD 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.

ADDITIONAL INFO
If this computer is a domain controller for the specified domain, it sets up the secure session to the primary domain controller emulator in the specified domain. Otherwise, this computer sets up the secure session to any domain controller in the specified domain.
