   Track NetBIOS over TCP/IP statistics


■    Show the details of incoming and outgoing NetBIOS over TCP/IP connections


■    Resolve NetBIOS names


Because NetBIOS name resolution is primarily a Windows 95/98 or Windows NT network issue, the nbtstat command is available only on Windows 95/98 and NT networked computers.


To display a basic description of nbtstat and its associated options, type nbtstat at the command line. You’ll use these options to configure the display of information about NetBIOS over TCP/IP hosts. Here are some of the switches you can use:


-a


-A


-c


-n


-r


-R


-S


-s


All nbtstat switches are case sensitive. Generally speaking, lowercase switches deal with NetBIOS names of hosts, and uppercase switches deal with the TCP/IP addresses of hosts.


The -a Switch


The -a switch displays a remote machine’s NetBIOS name table, which is a list of all the NetBIOS names that that particular machine “knows about.” The following command produced the output for the server S1 shown in Figure 4.5:


C:nbtstat -a S1
