Hi All,

I am using Jcifs 1.3.8_tb in my application and can not use the latest jcifs

We have been testing our app which requires reading data from a Cifs share,
when testing with Windows 2008 R2, unfortunately it does not seem to work.

We get the following exception which seems to be at the authentication

smbtransport: new connection<00>/ 445 administrator

As this seems to be an authentication issue. is there a way to use Jcifs
version 1.3.8 with Windows 2008 R2?

With the latest version of Jcifs (version 1.3.16) application works fine and
I am able to read the remote directory and list files, but I am not able to
get some file metadata which I can with 1.3.8 which is why I have to use the
older version of jcifs.

Any help to get the 1.3.8_tb version working with windows 2008 R2 and
similar with or without a third party product would be most helpful.

Many Thanks in advance for any guidance.
