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

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

SYMPTOMS
========

The Microsoft Exchange Message Transfer Agent (MTA) will generate a 2171 Event
ID in the Windows NT Event Log and stop making associations to other MTAs.

CAUSE
=====

This problem is due to the extremely large numbers of Remote Procedure Calls
(RPC) made when the Microsoft Exchange Sites and the Microsoft Exchange Servers
are in a hub configuration and there are a lot of Microsoft Exchange Servers in
a single Microsoft Exchange Site.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem was corrected in Microsoft Exchange Server 4.0 U.S.
Service Pack 2. For information on obtaining the service pack, query on the
