Nbtstat command
Updated: 11/12/2023 by Computer Hope
Nbstat is a utility that displays protocol statistics and current TCP/IP connections using NBT (NetBIOS over TCP/IP), which helps troubleshoot NetBIOS name resolution issues. Normally, name resolution is performed when NetBIOS over TCP/IP is functioning correctly. It does this through a local cache lookup, WINS or DNS server query or through LMHOSTS or hosts file lookup.
