PRODUCT :Microsoft Exchange
PROD/VER::5.5 SP4

KEYWORDS:kbExchange550preSP5fix

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

 - Microsoft Exchange Server, version 5.5 SP4 
-------------------------------------------------------------------------------


SYMPTOMS
========

If an incoming connection times out before the Exchange Server 5.5 message
transfer agent (MTA) receives the OK response, the MTA may generate an event ID
4283 error message.

The MTA generates at least the following two events:

   

   message NMI4258: Interface Event, severity 8

          (POP4 POP4 UP(7) Proc 228) 02-26-02 02:43:50pm
          Message received at NSI:
            cb 12
            LPI 1-15-12
            Message type Close Request

   later
   message NMI4283: Interface Event, severity 14

          (POP4 POP4 UP(7) Proc 228) 02-26-02 02:43:50pm
          Bad LPIs in message
          Bad LPI 1-15-12
          Error code = 8464

CAUSE
=====

The problem may occur if the system cannot respond to incoming connections
before the connection times out at the Winsock layer.
