Technical description for port 137:

Port 137 is a Net Service protocol within a NETBIOS. It is a main requirement for Microsoft users operating mostly on networking platforms such as Windows 9x, ME, NT and Windows 2000. Commonly, these operating systems specialize in networking topology.
Port 137 is a code of behavior providing functions for log-on sequence, pass-thru validations, trust support, Windows System Registration, and Windows NT Secure Channel. These are all related to network and stream security.
Port 137 uses two protocols to stream the values of communication, the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). These are transport layer protocols enabling the connection to pass through not only via local network but also via Internet. This is called Internet Protocol Suite. These functions are commonly known as TCP/IP. These functions use a protocol to communicate for the network, transport, and session layer. These procedures are responsible for data sharing by running a program using another computer from the user's computer. An example of this is the playback of an MP3 file in another user's computer via the network.
