nbtstat command

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.

Availability

Nbtstat is an external command that is available for the following Microsoft operating systems as nbtstat.exe.

-S Shows sessions by IP address. Lists sessions table with the destination IP addresses.
