The file and printer sharing firewall ports are currently closed.  This is the default configuration for a system that is not sharing content or is on a Public network.

Guidance:

You should expect this event when Windows Firewall is not configured to enable the File and Printer Sharing rule, which allows inbound SMB traffic. This event occurs on a computer that does not have custom shares configured. Clients cannot access SMB shares on this computer until SMB traffic is allowed through the firewall.
