[Eric.Mitchell at wellsfargo.com]

My typo in the email. :o) 
I do have all URL's ending with a slash.

Ok, so it does have something to do with the new changes because
smb://servername/dfsshare works with 1.2.13 and does not with 1.2.17. I'll
see if I can replicate that issue here.

Also, SMB URLs that refer to directories must end in a slash. I don't know
if that has any impact but please try adding a slash and see if that makes
any difference.

Mike
