Unless you're doing something bad like using multiple threads with the
same SmbFile instance, the "parameter is incorrect" error should never
occur and thus this would be a bug.

The fastest way to find out what's going on is to get a packet
capture. If you do get a packet capture of the error, make sure you
send it to me directly. Do not post packet captures to public mailing


PS: It's considered very bad form to use credentials in the URL. Use
(and re-use) an NtlmPasswordAuthentication object.
