nbtstat

The nbtstat utility is used to view protocol statistics and information for NetBIOS over TCP/IP connections. nbtstat is commonly used to troubleshoot NetBIOS name resolution problems. Because nbtstat provides the resolution of NetBIOS names, it's available only on Windows systems.

A number of case-sensitive switches are available for the nbtstat command. Table 6 summarizes these switches.
