Send Connector Disabled

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

The Microsoft Exchange Analyzer Tool uses the following Exchange Management Shell cmdlet to query for all Send connectors in the Exchange environment that have the value of their Enabled attribute set to False. A value of False for the Send connector Enabled attribute indicates that the Send connector is disabled.

Get-SendConnector | where { $_.Enabled -eq $False}

The Exchange Analyzer then queries the Active Directory directory service for the value of the serialNumber attribute for all objects with an object class of msExchExchangeServer.

If the string value includes Version 5.5, the computer is running Microsoft Exchange Server 5.5. If the string value includes Version 6.0, the computer is running Exchange 2000 Server. If the string value includes Version 6.5, the computer is running Exchange Server 2003. If the string value includes Version 8, the computer is running Exchange Server 2007.

If the Exchange Analyzer determines that a Send connector is disabled in an Exchange environment that also has Exchange 2000 or Exchange 2003 servers, the Exchange Analyzer displays an error.

This error indicates that while Exchange 2007 routing will ignore disabled Send connectors, Exchange 2000 and Exchange 2003 will not recognize the disabled flag for the connector and may still attempt to route messaging through the connector resulting in routing loops.

To address this error, delete any disabled Send connectors in Exchange environments that are running Exchange 2000 or Exchange 2003.

To delete a disabled Send connector, follow the guidance for using the Exchange Management Shell Remove-SendConnector cmdlet in the "Remove-SendConnector" ( topic of the Exchange Server 2007 product documentation.
