NetBIOS over TCP/IP

NetBIOS over TCP / IP ( NetBT or NBT short ) is a network protocol that allows building on the NetBIOS programming interface programs through the network TCP / IP protocol to use.

NBT is 1002 ( Details ) defined in the RFC documents RFC 1001 ( overview) and RFC.

The NetBIOS name resolution over UDP on port 137, the Datagram Service over UDP on port 138 and the Session Service over TCP on port 139. The UDP packets and TCP connections carry at the beginning of each header with information such as the NetBIOS name of the sender and receiver.

Older versions of Windows used ( up to Windows ME) NBT to the higher network functions (Server Message Block (SMB ) ) to realize. Newer Windows versions (from Windows 2000 ) handles SMB communications from directly over TCP port 445.
