PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:exc55 EXC55SP3Fix

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

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


SYMPTOMS
========

In some cases, a third-party X.400 message transfer agent (MTA) may send an
invalid message to Exchange Server. Depending on the amount of corruption, the
following events may be written to the Windows NT Server application event log:

   Event ID: 200
   Description:
   X.400 Service Event, severity 14
   (MTA XFER-IN(12) Proc 102)
   Transfer-In failure, error in received APDU
   Syntax server error code 0
   Error detected at offset 0
   Internal qualifier 0
   Node label
   PDU dump reference 14

NOTE: Event ID 200 indicates a corrupted field in the X.400 P1 message header.
You can use the PDU dump reference given in this event to identify the corrupted
message in the Bf0.log log file.

   Event ID: 2124
   Description:
   Internal Operating System Error, severity 14
   (DB Server XFER-IN(12) Proc 98)
   Object Data file causing I/O error
   Object id 06000091
   Operating system error 131
   File operation READ
   File offset -2133778432
   Filename
   Referenced object 00000000 (00000000 => N/A)
   Referenced object error 0

   Event ID: 2175
   Description:
   Internal Processing Error, severity 14
   (DB Server XFER-IN(12) Proc 72)
   Error getting length of attribute
   Called from MTA Proc 28492
   Database error code ODXOBJEC - I/O Error on object file
   Object at fault 06000091
   Attribute identifier 71
   Value number 2
   Referenced object 00000000 (00000000 => N/A)
   Referenced object error 0

After this, the Exchange Server MTA may run at a very high CPU time for a long
time and occasionally it may not be possible to stop the Exchange Server MTA.

version 5.5. For additional information, please see the following article in the
