Hi Jim,

The oldest and only version of SMB supported by JCIFS is "NT LM 0.12"
which has been used almost exclusively since the introduction of
Windows NT 4.0 back around 1997 or there abouts. There is an SMB2 now
that JCIFS does not support. JCIFS just does SMB and not SMB2. But
SMB2 is not widespread yet and I expect Windows will maintain backward
compatibility for at least as long as their clients use regular SMB
(which last I checked was all of them).
