This SMB URL should never generate such an error. Pls post your
test.properties file.

This error occurs when you try to list the IPC$ share like:

java -Djcifs.properties=test.properties ListFiles "smb://filer/IPC$/"

which is of course invalid. One thing that you might not realize is
that listing each node returned by listing "smb://filer/" will attempt
to list IPC$ and printers which is again invalid.

Also, what version of JCIFS are you using and what is the server
(e.g. Windows2000)?
