Jun 10, 2020 · SMB was originally designed by Barry Feigenbaum at IBM in 1983 with the aim of turning DOS INT 21h local file access into a networked file system and was originally designed to run on top of NetBIOS over TCP/IP (NBT) using IP port 139 and UDP ports 137 and 138.
I think this is probably a mistake as some ancient Unix services operated over TCP and UDP on the same port number.

May 15, 2019 · SMB over TCP vs. SMB over NBT. One central task for the SMB (Server Message Block) protocol is file sharing. In Windows NT it ran on top of NBT (NetBIOS over TCP/IP), which used the famous ports UDP 137 and 138, and TCP 139. With Windows 2000, Microsoft added the option to run SMB directly over TCP/IP, without the extra NBT layer. As can be seen above, Samba uses both the UDP and TCP protocols. TCP is used for file and printer sharing on port 139. UDP is used for the registration and translation of NetBIOS names, and for browsing the network. Port 137 is used for name service requests and responses. Feb 27, 2019 · The nmbd service provides NetBIOS over IP naming services to clients and listens on UDP port 137.
