Network Administration: The nbtstat Command

nbtstat is a Windows-only command that can help solve problems with NetBIOS name resolution. (nbt stands for NetBIOS over TCP/IP.) You can use any of the switches to specify what nbtstat output you want to display. For example, you can use an -a switch to display the cached name table for a specified computer, like this:

C:>nbtstat -a WK07-001
Local Area Connection:
Node IpAddress: [192.168.1.110] Scope Id: []
           NetBIOS Remote Machine Name Table
       Name               Type         Status
