Remote Queue length beyond threshold

[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. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft Exchange Analyzer Tool includes a performance data collection engine that is used to query performance counter objects on computers that are running Exchange 2000 Server or Exchange Server 2003. The performance data collection engine collects data from the Remote Queue Length performance counter of the SMTP Server performance object to analyze performance data.

If the Exchange Analyzer determines that the Remote Queue Length counter has exceeded the peak value of 1000 during the sample time slice, the Exchange Analyzer displays an error.

The SMTP Server\Remote Queue Length counter indicates the number of messages in the Simple Mail Transfer Protocol (SMTP) queue waiting for remote delivery. An increase in the Remote Queue Length means that mail is not being sent to other servers.

This failure to send mail can be explained by outages or performance issues with the network or remote servers. Those outages or performance issues prevent the network or remote servers from receiving the mail efficiently.

To resolve this error, use the resources in the following links to identify the problematic server or network component and address the performance issues.
