[jcifs] DFS Questions

[Jake Goulding]

I have a user who is trying to access files on a DFS mount. As I 
understand it, this is a large organization and the user directories for 
everyone are stored on a DFS share. They are doing a little test of a 
directory with 4 files in it. Sometimes the directory will list, 
sometimes not. Sometimes a file will be retrieved correctly, most times not.

When an exception occurs, it is always on the first remote operation 
that I use: SmbFile.exists(). The exception is:

jcifs.smb.SmbException: The network name cannot be found.
	at jcifs.smb.SmbTransport.checkStatus(SmbTransport.java:514)
	at jcifs.smb.SmbTransport.send(SmbTransport.java:614)

	at jcifs.smb.SmbFile.queryPath(SmbFile.java:1195)
	at jcifs.smb.SmbFile.exists(SmbFile.java:1277)


I am not particularly familiar with DFS, so any help is greatly 
appreciated. Perhaps I need to set some options that I am unaware of? 
Maybe there is some way of telling if a server is DFS and set those 
options automatically?

Thanks!
