It looks like you're trying to access the file through your mapped drive
(i.e., you have some shared drive mapped to your local "O:" drive).  If you
want to access the resource using jCIFS, you would need to target the server
directly via an SMB URL.  For example, if "O:" is mapped to the share
"svrshare" on server "myserver", you would do:

    new SmbFile("smb://myserver/svrshare/SQLNET/TNSNAMES.ORA");

If you want to access it using the mapped name (i.e., "O:"), you should be
able to do this with just a normal java.io.File:

    new java.io.File("O:\\SQLNET\\TNSNAMES.ORA");
