There seems to be no definite rule in SMB as to whether a string will
be null-terminated or not. The closest approximation seems to be that
those strings that have an explicit length field are not null
terminated, whereas other strings are. Unfortunately there are several
examples where this rule is violated, usually by strings that have
both and explicit length field and null termination.
Windows NT seems to be usually quite tolerent of adding null
termination where it is not required. Unfortunately some other servers
are much fussier (particularly NetApp).
Perhaps the trickiest thing to work out is whether explicit length
fields should include the null termination or not. In most cases it
doesn't matter, but there are some notable exceptions.
