What is the CIFS server you are communicating with?

The NT_STATUS_BAD_NETWORK_NAME "The network name cannot be found." error
means it cannot locate the share.

If it works with explorer get a capture [1] of it working with Windows
2000/XP/2003 and another capture of jcifs failing with the same exact
parameters. Then I can figure out what the difference is. I think the
problem might be that I never tested having a dfs mapping that is the
share itself. I didn't know you could do that actually.

That's NT_STATUS_NO_SUCH_DEVICE "The system cannot find the file
specified."

I can't tell. You're using jcifs correctly. It either a server
configuration error or a bug in JCIFS. I would really need the captures
to determine what the problem is.
