Not only that, but you can also connect by specifying the IP, ala
\\a.b.c.d\share, which will make another TCP connection.  And then
there are the non-MS clients which may do other things, as well.  I
have some SMB client code which makes multiple connections to a given
server, even with the same netbios name.  Each connection has to
specify a different vc_no in the SMB session setup, or NT will reset
one of the TCP connections, but it does work.
