Article: Q263710
Product(s): Microsoft Exchange
Version(s): winnt:5.5 SP3
Operating System(s): 
Keyword(s): exc55sp3
Last Modified: 28-OCT-2000

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

- Microsoft Exchange Server, version 5.5 SP3 
-------------------------------------------------------------------------------

NOTE: If the Exchange Server computer that performs directory replication in your system does not have an anti-virus application
programming interface (API) mode virus scanner installed, this article does not apply.

SYMPTOMS
========

Replication between sites may stop working sporadically and the following event
IDs may be logged on the directory replication bridgehead servers:

  Source: MSexchangeDS
  MessageId=1102
  Severity=Warning
  During intersite replication, the directory replication agent (DRA) closed the
  connection to the mail service in response to error %1. Will attempt to
  connect again later.

  Source: MSexchangeDS
  MessageId=1103
  Severity=Warning
  During intersite replication, the directory replication agent (DRA) received a
  non-delivery report (NDR) for messages submitted for the directory at %1. The
  diagnostic is %2. The reason is %3.

CAUSE
=====

This issue can occur because Exchange Server 5.5 Service Pack 3 makes
virus-scanning APIs available to speed up attachment scanning.


Because of this, certain replication problems can occur if the replication
messages contain attachments. For additional information, click the article

article:

  Q262491 XADM: Information Store Crashes When Using Antivirus Application
