Source: https://learn.microsoft.com

Nbtstat is a Windows utility that helps in troubleshooting NETBIOS name resolution problems. The nbtstat command removes and corrects preloaded entries using several case-sensitive switches. Attackers use Nbtstat to enumerate information such as NetBIOS over TCP/IP (NetBT) protocol statistics, NetBIOS name tables for both local and remote computers, and the NetBIOS name cache.

nbtstat is a command-line tool in Windows used to display network statistics related to the NetBIOS over TCP/IP (NBT) protocol. It provides information about the network connections, including NetBIOS name resolution and the status of remote systems.
