A diagnostic tool for NetBIOS over TCP/IP. Its primary design is to help troubleshoot NetBIOS name resolution problems.

The common parameters are:

• nbtstat -c: displays the contents of the NetBIOS name cache, the table of NetBIOS names and their resolved IP addresses.
• nbtstat -n: displays the names that have been registered locally on the system.
• nbtstat -r: displays the count of all NetBIOS names resolved by broadcast and querying a WINS server.
• nbtstat -R: purges and reloads the remote cache name table.
• nbtstat -RR: sends name release packets to WINs and then starts Refresh.
• nbtstat -s: lists the current NetBIOS sessions and their status, including statistics.
• nbtstat -S: lists sessions table with the destination IP addresses.
