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.
