NBTSTAT

Nbtstat.exe is a useful tool for troubleshooting NetBIOS name resolution problems. You can use the nbtstat.exe command to remove or correct preloaded entries.

·         To list the NetBIOS table of the local computer, type nbtstat -n at the command prompt, and then press ENTER. This command displays the names that were registered locally on the computer by programs such as the server and redirector.

·         To list the contents of the NetBIOS name cache, type nbtstat -c at the command prompt, and then press ENTER. This command shows the NetBIOS name cache, which contains name-to-address mappings for other computers.

·         To purge the name cache and reload it from the LMHOSTS file, type nbtstat -r at the command prompt, and then press ENTER.

·         To perform a NetBIOS adapter status command against the computer that you specify by name, type nbtstat -a NetBIOS computer name at the command prompt, and then press ENTER. The adapter status command returns the local NetBIOS name table for that computer and the MAC address of the network adapter.

·         To display a list of client and server connections, type nbtstat -s at the command prompt, and then press ENTER. This command lists the current NetBIOS sessions and their status, including statistics, as shown in the following example:

   NetBIOS Connection Table 

 For example, to find out if your local machine is running NetBEUI/NetBIOS, type nbtstat -n on the computer. If it shows 'type' of '<20>', it is using NetBIOS. For a remote computer, type nbtstat -a computername or nbtstat -A IP.
