Article ID: 246278

Article Last Modified on 2/27/2007



APPLIES TO

  • Microsoft Exchange Server 5.5 Standard Edition
  • Microsoft Exchange 2000 Server Standard Edition



This article was previously published under Q246278

SYMPTOMS

When you use Exchange Server 5.5 or Exchange 2000 Server, mail may back up in connector queues. When you ping the destination server, you may receive either slow responses or complete timeouts. Also, Event Viewer may display the following events:

Event ID: 289
Source: MSExchangeMTA
Type: Warning
Category: X.400 Service
Description: A connection to /O=OrganizationName/OU=SiteName/CN=Configuration/CN=Connections/CN=ConnectorName could not be opened. [MTA XFER-IN 17 26] (12)

Event ID: 1294
Source: MSExchangeMTA
Type: Warning
Category: X.400 Service
Description: An association with entity /O=OrganizationName/OU=SiteName/CN=Configuration /CN=Connections/CN=ConnectorName ended abnormally. [198 1 0 1 PLATFORM KERNEL 20 130] (10)

CAUSE

This behavior can occur because of network-related problems that are external to Exchange Server performance. When there is not enough network bandwidth for any additional traffic, the message transfer agent (MTA) cannot create the necessary connections.

RESOLUTION

To resolve this issue, troubleshoot network connectivity and bandwidth issues.
