Hi,
thanks for the great details,
>>Then it gave me (no exception):
>>smb://testw2k3/temp
>
>
> This is wrong. There should be a trailing slash like
smb://testw2k3/temp/
in the code I found (smbfile.java):
String unc; // Initially null; set by
getUncPath; never ends with '/'
and (in getdfspath):
return "smb:/" + (new String( dfsReferral.node + unc
)).replace( '\\', '/' );
for me it is logical that the "/" is missing at the end, bug ?
In more detail (is it ok that there is a
"java.net.SocketTimeoutException: Receive timed out" ?):
(for the rest, see the ethereal dump attached)
I configured dfs to link to \\192.168.0.5\temp (I cannot use
\\192.168.0.5\temp\ because windows says it is not a valid unc-path)
my code:
SmbFile f = new SmbFile(
"smb://administrator:admin@192.168.0.5/MyRoot/testlink/" );
System.out.println( f.getDfsPath() );
the results:

> Sure. The way DFS works is it's basically a redirection mechanism. If jCIFS connects to 192.168.0.5/MyRoot/ and queries the path /testlink and it's "InDfs" the client should get an error STATUS_PATH_NOT_COVERED. That will trigger JCIFS to query the server for a "referral". The referral response should contain the server and path that corresponds to the DFS link (e.g. testw2k3 and path /temp). Then JCIFS will try to communicate with smb://testw2k3/temp/ like any other target. This of course involves a name lookup for 'testw2k3' so if that name is not valid you will get an error.
