The above property is invalid.

I'm not sure why this error would occur. The only think I can think of
that might cause an error like this is if you tried to use multiple
threads with the same SmbFile instance.

There is a bug in JCIFS where if you use an IP address instead of a
hostname in an SMB URL with a stand-alone DFS root, you can get this
error. But if you're really using a URL as shown above this is not the
issue.
