8bf = 2239 and net helpmsg says its "The user account has expired"
but I'm not sure that makes a whole lot of sense.

Niether can jCIFS. This is a limitation in the NetShareEnum RAP function.

A program should be written to model the concepts of the task it
performs rather than the physical world or a process because this
maximizes the potential for it to be applied to tasks that are
conceptually similar and, more important, to tasks that have not
