Store: HTTP port is non-default

[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.]  

Topic Last Modified: 2007-01-09

The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine whether HTTP Port is set to the default value:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem\Rpc/HTTP Port

If the Exchange Server Analyzer finds that the value for Rpc/HTTP Port is not 6001 (decimal), a non-default configuration message is displayed.

The Rpc/HTTP Port registry key is set to 6001 by Exchange Server 2003 and Exchange Server 2007 Setup. The Rpc/HTTP Port registry key is used to support RPC over HTTP functionality for Microsoft Office Outlook® 2003 and Microsoft Office Outlook 2007.

Unless you have customized your RPC over HTTP deployment with the aid of Microsoft Consulting Services or by recommendation from Microsoft Product Support Services, it is recommended that you deploy RPC over HTTP with the default port values.
