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.
