NetBIOS (Network Basic Input/Output System) is a program that allows applications on different computers to communicate within a local area network (LAN). It was created by IBM for its early PC Network, was adopted by Microsoft, and has since become a de facto industry standard. NetBIOS is used in Ethernet and Token Ring networks and, included
NetBIOS Name Service (NBNS) This service is often called WINS on Windows systems.. The NetBIOS Name Service is part of the NetBIOS-over-TCP protocol suite, see the NetBIOS page for further information.. NBNS serves much the same purpose as DNS does: translate human-readable names to IP addresses (e.g. www.wireshark.org to 188.8.131.52). (As NetBIOS can run on top of several … NetBIOS over TCP/IP - Wikipedia NetBIOS over TCP/IP (NBT, or sometimes NetBT) is a networking protocol that allows legacy computer applications relying on the NetBIOS API to be used on modern TCP/IP networks.. NetBIOS was developed in the early 1980s, targeting very small networks (about a dozen computers). Some applications still use NetBIOS, and do not scale well in today's networks of hundreds of computers when NetBIOS is Port 137 (tcp/udp) :: SpeedGuide

This disables the Nbt.sys driver, which stops NetBIOS from listening to or initiating sessions over TCP 139. While SMB normally uses this port for communication, it will now switch to TCP 445 Netstat Command in Linux with Examples - LinOxide Netstat is a command line tool that is used to view and monitor network statistics and configurations of a system. This tool is available on both Unix, Linux and Windows NT-based operating systems.

Unexplained NETBIOS traffic - Wireshark Q&A Yes, NetBIOS-over-TCP can go out over the Intertubes, because it runs atop IP. However, it's generally not sent out across the Atlantic Ocean; unless he's working for an international company with offices in Europe, and the machines in question have reasons to do, for example, SMB across the Atlantic to machines in Europe, those packets are a bit suspicious - I doubt any Windows domains set up
