From Wikipedia, the free encyclopedia 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).
NetBIOS is legacy, there is really small chance you can find any place still using such old technology. It should not be needed at all unless you still have some very ancient legacy non-TCP application that needs some sort of session layer naming Apr 06, 2005 · As a result, some administrators are tempted to disable NETBIOS over TCP/IP entirely on Windows 2000 or later machines. Before you do this however, you should know the possible side effects. One of the unexpected consequences of disabling NetBIOS completely on your network is how this affects trusts between forests. Older OSes ran NetBIOS over Ethernet, IPX/SPX using NetBIOS Frames (NBF) Now mostly NetBIOS over TCP/IP (NBT). (NetBIOS is now used as synonym for NBT) Nodes have a NetBIOS name and an IP address. NetBIOS over TCP/IP services. Standardized in. RFC 1001; RFC 1002; Provides: + Name Service (Port 137/UDP) + Datagram Service (Port 138/UDP A Microsoft-created protocol that enables NetBIOS naming information to be transported over TCP/IP networks. The result is that Microsoft naming services can operate on a TCP/IP networking without the need for DNS services. Uses TCP ports 137 and 139, and UDP ports 137 and 138. To resolve IP addresses to computer names, Azure ATP sensors look up the IP addresses using the following methods: NTLM over RPC (TCP Port 135) NetBIOS (UDP port 137) RDP (TCP port 3389) - only the first packet of Client hello; Queries the DNS server using reverse DNS lookup of the IP address (UDP 53) Dec 05, 2018 · TCP/139 – NetBIOS Session Service: This is perhaps the most known Windows port of all, as it is used to transfer files over TCP. This is both the port that NULL Sessions are established over and the port that file and printer sharing takes place on. While there's NetBIOS for TCP, you can actually have it work without an IP address at all. It should not be needed at all unless you still have some very ancient legacy non-TCP application that needs some sort of session layer naming service. If you are machine has an IP and DNS, you can join it to the domain using the full domain suffix.

ARP resolution, Microsoft Endpoint Mapper, NetBIOS - THWACK MOST of my computers are not getting detected correctly, still getting the following error: The MAC address retrieval using ARP resolution was not attempted for 192.168.X.X because the ICMP ping failed. Unable to retrieve NetBIOS domain name and computer name. Unable to establish a TCP connection to
The charts below list all possible network communication ports used when ESET Remote Administrator and its components are installed in your infrastructure. Other communication occurs via the native operating system processes (for example NetBIOS over TCP/IP). ERA Server:
In this case, it acts as a session-layer protocol transported over TCP/IP to provide name resolution to a computer and shared folders. NetBIOS uses these ports: UDP 137: NetBIOS name service NetBIOS over TCP/IP - ZyXEL | DSLReports Forums Nov 21, 2005
