Subject: 23.3.1 NT: UAC permission and network drive path problems
Date: Fri, 09 Dec 2011 19:53:35 +0200

Package: emacs
Version: 23.3.1
Severity: normal

TEST CASE

    - OS: Windows 7 64 bit
    - Log in as standard user
    - Start Emacs with "run as administrator"
    - Map remote host to a drive letter
    - Try accessing remote drive, like z:/ e.g. with
      C-x d <drive path>[TAB]

    This causes signallling a cryptic error

SUGGESTION

    Improve error condition checks, missing or non accessible location, and
    display more informative error message.
