KB927891 causes CD/DVD access to be prohibited

    I installed KB927891 today and shut down my Windows XP Pro system. Upon
    restarting the system, I discovered the following error:

    "Administrator has prohibited access to CD/DVD ROM drives."

    A similar error pops up if I attempt to use a USB drive.

    This is an unacceptable situation, as I have no access to any external
    drives or resources. I have tried to uninstall this particular Windows
    Update, but the error persists.

    Any suggestions on how to return my system to a usable state?

  2. Hi Dr. PDX,

    A search of the "Administrator has prohibited access to CD/DVD ROM drives."
    error message revealed two separate threads where uninstallation of the
    "Desktop Utilities" program (one had Acer Desktop Utilities and the other had
    Intel Desktop Utilities) resolved the problem.

    I, too, came across the same threads referring to Desktop Utilities, but I
    decided to ignore the "solutions" they suggested because my installation of
    Intel Desktop Utilities (IDU) has been the same for a year+. But, in good
    conscience, I couldn't respond without at least giving it a try.

    As luck would have it, uninstalling the IDU package returned my system to a
    usable state -- all CD, DVD, and removeable media drives were accessible
    again. However, all of the drive icons in "My Computer" switched from
    regular icons to "unknown" icons.

    Since I was already in experimental mode, I reinstalled IDU and everything
    is once again back to normal.

    I can't explain it. And it really doesn't make any sense. But Patch
    KB927891 clearly conflicts with various brands of desktop utilities (Intel
    for sure) and the "fix" is to uninstall and reinstall.

    For those who run into this problem in the future: I found that System
    Restore does *not* work to repair this problem. My advice is to follow the
    uninstall/reboot/reinstall sequence and see what happens.

    Good luck. And a big thanks to Patti for the push I needed to fix this!

  4. You're very welcome, Dr. PDX :)

    And thank YOU for the additional info (change in drive icons). So, I am
    assuming that the reinstall of Desktop Utilities did not cause a recurrence
    of the prohibited access problem.
