SYMPTOMS
========

If you use a backup program on a multiprocessor computer that uses a buffer
setting of more than 64 kilobytes (KB), the backup program does not detect a
corrupted page during the online backup. The database is backed up successfully,
even though it is corrupted.

The online backup program successfully detects the corrupted page on a single
processor computer, regardless of the buffer setting.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server 5.5.
