   SMB used to be layer on top of NetBIOS which could be layered on top =
of TCP/IP among others protocols.  With Windows 2000 SMB is supported =
hosted directly on TCP/IP.  This is what port 445 is used for.  There is =
also direct hosting of SMB on IPX which I think was introduced in = Windows
9x.

   NetBIOS has applications other than SMB.  You probably can =
applications that use NetBIOS if you look.

  This article makes it sound like netbios over tcp is only required for =
pre-
  Windows 2000 support:

  However, I am still confused by what exactly netbios does and what its =

  relationship is to SMB, file sharing, and network browsing.
