What are three methods of NetBIOS resolution?

The three standard ways of resolving NetBIOS names to IP addresses are through a local broadcast, using the local cache, or by using a NetBIOS name server.

Which utility will help solve problems with NetBIOS name resolution?

Why are NetBIOS over TCP / IP and LLMNR disabled?

By default, NetBIOS over TCP/IP support is enabled for all interfaces in all Windows versions.
