More info:

The next dir down that gave the above error is read-only.  As is even the next
level down from there (and I have no control on those permissions).  But then at
the next level down there are dirs that I can read and write to and if I type
all that path to start with, things start working.  I am able to dired, copy etc
etc from those dirs.

If I run smbclient from a shell window command line, I can cd to each of the
dirs that are read-only, do dirs etc and see the contents, so I think this
means that it is not the settings on the dir itself blocking tramp, but rather
something tramp detects as a problem when it isn't.  AFAICT, the read-only
attribute is the only thing different between dirs I can dired and those I 
can't.

This sound reasonable?  

Thanks
tom

ps I still have to do a "g" on each dir I go to.
