Information
NetBIOS over TCP/IP is a network protocol that among other things provides a way to easily resolve NetBIOS names that are registered on Windows-based systems to the IP addresses that are configured on those systems. This setting determines whether the computer releases its NetBIOS name when it receives a name-release request. The NetBT protocol is designed not to use authentication, and is therefore vulnerable to spoofing.
Solution
