Works for me if the server called "server" exists, but has no
share named "junk".

  bash$ ls -ls //server/junk
  ls: cannot access //server/cygwinx: No such file or directory

The noticable difference is that the access returns another error
on the Win32/native NT level:

  C:\>dir \\server\junk
  The network name cannot be found.

So there's YA error possible when accessing a non-existant share.
Great!  To fix this for Cygwin 1.7.7, I need an strace from you:

  bash$ strace -o share-logon-failure.trace ls //server/junk

Just send the share-logon-failure.trace file as attachment.
