The system cannot find the path specified

[Coppens Benoît (All4IT)]

Hi,
 
I'm using the following code to retrieve a document from a DFS:
 
********************
public static void main(String[] args) {

  try {

    jcifs.Config.setProperty( "jcifs.netbios.wins", "10.1.253.2" );
    NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("UCB-CORP", "E118616", "password");
    SmbFile fileToGet = new SmbFile("smb://ntbrafscl011.dir.ucb-group.com/dfs/Sites/Braine/GTSO/GECTD/DSPE/Department organization/Archives/Time sheet/TS SVL SVT JLH - 060504.xls", auth);
    SmbFileInputStream in = new SmbFileInputStream(fileToGet);
    byte[] b = new byte[8192];
    int n;
    while(( n = in.read( b )) > 0 ) {
      System.out.write( b, 0, n );
    }

  }
  catch (Exception e) {
    e.printStackTrace();
  }

}
********************

If I use jcifs-1.2.18.jar, it works fine.
If I use jcifs-1.2.21.jar, it does not work and the error is:

********************
1: new Socket: java.net.DatagramSocket@54172f
2: new Socket: Socket[addr=/10.1.253.2,port=445,localport=3262]
3: new Socket: Socket[addr=/10.1.12.155,port=445,localport=3263]
jcifs.smb.SmbException: The system cannot find the path specified.

********************

What could be the reason?

Thanks a lot,
Benoit

The DFS code was changed significantly recently. Previously we didn't
fully understand how referrals were used to discover DFS topology at
the roots. We just iterated overall all IPs for the supplied server
name until we found what we were looking for. It was crude but it
worked. That code is now superseded by proper DFS referral code that
looks up and caches the list of trusted domains and then looks up and
caches which server is hosting the target share and so on. So that
could be a factor in your issue.

To determine what the problem is you first need to determine if you're
using domain-based or stand-alone DFS. If you are using domain-based
DFS then is the following really a domain name or is it a full
hostname?

  ntbrafscl011.dir.ucb-group.com

Perhaps you want to use smb://dir.ucb-group.com/dfs... or
smb://ucb-group.com/dfs... etc?

Try going to a Windows client and do Start > Run and put in the
corresponding UNC path
\\ntbrafscl011.dir.ucb-group.com\dfs\Sites\Br...

Does it work? If it does but the corresponding smb:// path does not,
then that is an incompatibility with JCIFS that we should probably
fix.

If you determine that you are using stand-alone DFS (doubt it if the
share name is really 'dfs') then it's just a bug in JCIFS and I'll
have to convince you to send me captures.

Hi Mike,

The answer I got from our server team is:

ntbrafscl011.dir.ucb-group.com is the the host name of the stand alone DFS

If I enter "\\ntbrafscl011.dir.ucb-group.com\dfs\Sites\Braine\GTSO\GECTD\DSPE\Department organization\Archives\Time sheet\TS SVL SVT JLH - 060504.xls" in the Start > Run dialog, the file is opened in Excel

It works also with \\ntbrafscl011\dfs\Sites\...
But it does not work with \\dir.ucb-group.com\dfs\Sites\... or \\ucb-group.com\dfs\Sites\...

Let me know if you need more info.

Thanks a lot,
Benoit

Hi Benoit,

That is very possibly a bug in JCIFS then. It sounds like stand-alond
DFS is broken. I'll have to play with it and make sure it's working
properly. But I'm a little backed up right now. It might take me a
while.

What is the server? Windows 2003, Samba, ...?

Hi Mike,

This is Windows 2003.

Dear Mike,

I tested with version 1.2.23 but it does not fix my issue.
Stack trace is:

Hi Benoit,

Can you get a capture [1] of JCIFS failing and another of Windows
succeeding? That's the best way to see what's going on.

Dear all,

I confirm that 1.2.24 fixes the issue!

Thanks,
