Windows share browser goes to '/'

[pjcross]

For a shared drive on a regular Windows machine, not a corporate collaborative drive, the user was able to successfully login, but they couldn't see any files (the share had been the C drive). After some experimentation, replacing the '/' (which isn't a Windows location) with Users, the browser displayed the files in that directory. Going up from that location, the '/' reappeared in the field with the path, but the correct files were now visible in the file browser. I suspect that the initial landing spot of 'root' is the source of the problem, since for Windows that should be the C drive. Only once the file browser had been pointed to a valid location, could it actually find and return a file list.
