AW: [jcifs] DFS-Links and jcifs.smb.client.soTimeout

[Michael B Allen]

CC-ing jcifs mailing list again.

I don't understand this log. What am I looking for? Can you get a packet
catpure (http://jcifs.samba.org/capture.html)?

With NetworkExplorer exactly what happends? You click on a non DFS link
it's fine, but when you hit a DFS path it gives you the "Invalid access
to memory location" error?

Last I checked NetworkExplorer worked with DFS fine. I don't think I
have a DFS share on which to test it anymore though. I'll check.

There have been reports that jCIFS will not work with some DFS setups. It
has something to do with active directory. Clients somehow know in advance
what shares are DFS and do not attempt a referral. This is protocol that
I do not understand and is therefore not supported. If this turns out
to be the scenario there's not much I can do.
