Store HTTP port is below 5000
Topic Last Modified: 2007-03-21
The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the Rpc/HTTP Port setting for the Microsoft Exchange Information Store service:
If the Exchange Server Analyzer finds that the value for Rpc/HTTP Port is set to a value below 5000 (decimal), a warning 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.
If you must set Rpc/HTTP Port to a value other than 6001, it is recommended that you set it to a value that is just over 5000. Assigning static port numbers under 5000 may cause a port conflict with another process and lead to failure of the Microsoft Exchange Information Store service process.
