PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:exc55 kbExchange550preSP4fix kbExchange550sp4Fix kbgraphxlinkcritical

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

 - Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

During normal operation of the Exchange Server information store (Store.exe), if
a non-delivery report (NDR) is returned that has a blank e-mail address and
message tracking enabled, the Exchange Server information store service may stop
unexpectedly with an access violation when it tries to write the message details
to the tracking logs. If the correct Microsoft Windows NT and Exchange Server
debug symbols are installed, the resulting Dr. Watson log may contain a stack
dump that is similar to the following:

   

   0232fc4c  00412074  STORE!CchStrlenW
   0232fc60  00600c15  STORE!CchStrlen+0x88
   0232fd90  004fcef1  STORE!EcGenerateGWNDR+0xbc3
   0232ffa0  004dfd21  STORE!FStartTransferOut+0xd00

CAUSE
=====

This issue can occur if the Exchange Server information store erroneously
handled the NULL value for the NDR e-mail address when the Exchange Server
information store attempted to write the message details to the tracking logs.
This causes the Exchange Server information store to try to access invalid
memory.

RESOLUTION
==========

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