Article: Q190696
Product(s): Microsoft Exchange
Version(s): winnt:4.0,5.0,5.5
Operating System(s): 
Keyword(s): 
Last Modified: 22-OCT-2000

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Exchange Server, versions 4.0, 5.0, 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you try to start the information store, the following Event ID appears the
Windows NT event viewer application log:

  Event ID 116
  Source ESE97
  Type Error
  Category Database Page Cache

  MSExchangeIS ((52) ) Synchronous read page checksum error -1018
  ((1:1057816 1:3688618971) (3688618971-3688618971) (0-16815256))
  occurred. Please restore the databases from a previous backup.

NOTE: For versions 4.0 and 5.0, "Source" above is "EDB".

CAUSE
=====

The Microsoft Exchange Server computer has suffered from service database
corruption as a result of the Exchange database being compressed and growing
beyond 4 GB in size.

WORKAROUND
==========

To work around this problem, decompress the database drive, if applicable, and
restore from a backup.

If a good backup is not available, decompress the Priv.edb and Pub.edb files and
bring the database to consistency by performing an EDButil /r /ispriv and/or
/ispub for Exchange Server versions 4.0 and 5.0. For Exchange Server version
5.5, use ESEutil /r /ispriv and/or /ispub.

If the above steps are not successful, the database may need to be repaired to
bring it to consistency.

MORE INFORMATION
================

- Database compression is only one possible cause of -1018 errors.

- You may encounter the -1018 errors at any time, not just at startup.

- You may also get an asynchronous read page error with a different Event ID.
  Both are -1018 errors, however.
