TITLE   :XADM: Exchange Store Stops Due to Data Corruption
PRODUCT :Microsoft Exchange
PROD/VER:winnt:4.0
OPER/SYS:
KEYWORDS:kbnetwork exc4

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

 - Microsoft Exchange Server, version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Microsoft Exchange Information Store Service may terminate unexpectedly. The
Drwtsn32.log may show a failure of Store.exe with an entry similar to the
following:

   App: store.DBG (pid=248)
   When: 8/2/1996 @ 12:33:11.437
   Exception number: c0000005 (access violation)

CAUSE
=====

Data corruption of the Information Store causes an inconsistency, which in turn
causes a client request to make the server stop functioning.

WORKAROUND
==========

Run Isinteg.exe. This should fix the Information Store corruption, preventing
the failure.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem was corrected in Service Pack 3 of Microsoft Exchange
4.0. For information on obtaining the Service Pack, query on the following word
in the Microsoft Knowledge Base (without the spaces):
