About nbtstat

MS-DOS 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 done when NetBIOS over TCP/IP is functioning correctly. It does this through local cache lookup, WINS or DNS server query or through LMHOSTS or hosts file lookup.
