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

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


SYMPTOMS
========

If you connect two Exchange Server computers using a connector such as an X.400
Connector, and then remove the connector on one of the servers, the message
transfer agent (MTA) on the other server may stop responding (hang) if it
attempts to connect to the MTA on the first server. If you attempt to stop the
MTA on the other server, you are unable to do so.

CAUSE
=====

This issue occurs when the server on which the connector is removed has more
than one computer name associated with it. Under these circumstances, a remote
MTA may not properly increment an array index counter when it attempts to
connect to the MTA on the server.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server 5.5.
For additional information, please see the following article in the Microsoft
Knowledge Base:

version 5.5. This problem was first corrected in Exchange Server 5.5 Service
Pack 4.
