bug#10255: 23.3.1 NT: UAC permission and network drive path problems

[Jari Aalto]

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.

OUTPUT DATA

"GNU Emacs 23.3.1 (i386-mingw-nt6.1.7601) of 2011-03-10 on 3249CTO"

This is fixed on the trunk: I get "No match", as expected.

Bug closed.
