SYMPTOMS
========

When you start Microsoft Backup, your computer may stop responding (hang). Or,
you may receive the following error message:

   Microsoft Backup has encountered a serious error in the Tape Manager. Quit MS
   BAckup and all other programs then try again. If problem persist, reinstall
   MS Backup

CAUSE
=====

When you start Backup, it attempts to detect whether the computer contains a
tape drive. If Backup incorrectly determines that there is a tape drive when
there is not, the computer may hang.

RESOLUTION
==========

WARNING: If you use Registry Editor incorrectly, you may cause serious problems
that may require you to reinstall your operating system. Microsoft cannot
guarantee that you can solve problems that result from using Registry Editor
incorrectly. Use Registry Editor at your own risk.

To correct this problem, follow these steps:

1. Restart your computer.

2. Change the value for the TapeDriveDetected key from 1 to 0 in the following
   registry key:

      HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ 
      Applets\Backup

NOTE: If you have never run Backup successfully, the Backup key may not exist in
the registry. To create this key, restart your computer in Safe mode, run
Backup, quit Backup, and then restart your computer normally. You can then
follow the steps above.
