Just to be a little less terse...

Every Windows flavor since Windows/95 (inclusive) speaks the NT LM 0.12 
dialect.  Windows-for-Workgroups runs an earlier dialect (I have it 
written down somewhere, but it's one of the LANMAN dialects...).  That 
earlier dialect does not support some of the newer SMB messages, and some 
of the message formats have changed.

Multi-dialect support would require a mechanism to select which SMBs 
should be sent, and which format to use for each SMB.  It's do-able, but 
it doesn't appear as though the payback would be worth the effort or extra 
code-bulk.  As far as I know, this is the first request for WfWG 

Perhaps some of this should be in the FAQ...  Dunno.

How are you trying to use jCIFS?  Are you just trying to transfer files 
and such?
