NBSS: NetBIOS Session Service

The NetBIOS Session Service (NBSS) is one of two ways by which applications may communicate with each other, the alternative being the NetBIOS Datagram service. NetBIOS Session Service is for connection-oriented communications. NBSS lets two computers establish a connection for a "conversation", allows larger messages to be handled, and provides error detection and recovery. The bulk of all NetBIOS traffic generated on a network occurs using the NetBIOS Session service, which utilizes TCP port 139. File and printer services are the primary user of the NetBIOS Session service. Another common use for NBSS is the networked application: Server Manager, User Manager, Event Viewer, Registry Editor, and Performance Monitor.
