This means that the CIFS server is not listening on port 139. That means
jCIFS cannot even open a connection to the target server. That's not good.
JCIFS needs a server running an IPC$ pipe on a CIFS server on port 139
which is default behavior for all Windows operating systems. One
explaination for this could be that your network administrator has
disabled port 139.
