I didn't dive deep enough into this, but my XP client didn't even try 
connecting, it would just go straight to getting a DFS referral, and 
that seemed consistent with smbclient. How it made that decision, 
though, I really don't know.

I see. Won't ask any more questions. Thanks for fixing it! :-)

It merged easily into my 2.6.39.3, and that'll do for now. :-)
