             PROTOCOL STANDARD FOR A NetBIOS SERVICE
                     ON A TCP/UDP TRANSPORT:
                     DETAILED SPECIFICATIONS




                            ABSTRACT

This RFC defines a proposed standard protocol to support NetBIOS
services in a TCP/IP environment.  Both local network and internet
operation are supported.  Various node types are defined to accommodate
local and internet topologies and to allow operation with or without the
use of IP broadcast.

This RFC gives the detailed specifications of the NetBIOS-over-TCP
packets, protocols, and defined constants and variables.  A more general
overview is found in a companion RFC, "Protocol Standard For a NetBIOS
Service on a TCP/UDP Transport: Concepts and Methods".

1.  STATUS OF THIS MEMO
