The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the TCP/IP Port setting for the Microsoft Exchange System Attendant service:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeSA\Parameters\TCP/IP Port
If the Exchange Server Analyzer finds that the value for TCP/IP Port is set to a value below 5000 (decimal), a warning is displayed.
In the case where you must set TCP/IP Port to a static value, 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 System Attendant service process.
