Hi YLombardi,

Because you have no slashes in the SMB URL so the host and everything
else is ignored (by the java.net.URL class) and so you're doing the
equivalent of SmbFile("smb:").exists() which returns true.

You want something more like:

  NtlmPasswordAuthentication npa = new
NtlmPasswordAuthentication(domain, username, password);
  String url = "smb://server.busicorp.local/stuff/megafile.zip";
  SmbFile f = new SmbFile(url, npa);
  f.exists();

Look at the jcifs.smb.SmbFile API documentation for proper SMB URL syntax.
