NBTStat

NBTStat is a command-line tool that is designed to help troubleshoot NetBIOS name over TCP/IP resolution problems. It displays protocol statistics and current TCP/IP connections using NetBIOS over TCP/IP (NetBT). When a network is functioning normally, NetBT resolves NetBIOS names to IP addresses. Start NBTStat from the command prompt rather than from Windows Explorer to see the resulting display.
