[jcifs] jcifs.util.transport.TransportException: Connection timeout

[Keith]

Hi-
I'm just getting started with jcifs and am coming up with the following in a
test program.  I'm using jcifs1.2.7.jar.

I can't seem to figure out why it's failing ( thought it succeeds intermittently
), but it fails more than it succeeds, like 10:1.  

Looks like listFiles() is causing problems, and I saw a thread about 1.1.11 on
this, and then another about 1.2.7 solving some apparent issues, but ... I can't
seem to get any love.  It also doesn't seem to matter whether I authenticate or
not - I can get intermittently connections ( or failures, depending on whether
you stand on your head or your feet ) either way.

Any thoughts, ideas or updates would be fantastic!

Code :
...

try {
   System.setProperty("jcifs.util.loglevel", "0");
   System.setProperty("jcifs.netbios.wins", "10.10.10.10");
   System.setProperty("jcifs.netbios.retryTimeout", "20000");
   System.setProperty("jcifs.netbios.soTimeout", "30000");

   SmbFile f = new SmbFile("smb://");
   SmbFile[] files = f.listFiles();
} catch (Exception e) {
  // TODO : log exception
  ...

Error :
