MTA TCP/IP threads parameter is non-default
Topic Last Modified: 2007-11-14
The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine its current value:
If the Exchange Server Analyzer finds the value for TCP/IP threads present and set to anything other than 2, a non-default configuration message is displayed.
The TCP/IP threads value is the maximum number of message transfer agent (MTA) dynamic address module (DMOD) threads that handle RFC1006 connections. This number is multiplied by two for the two subtypes (
Async Notify) of RFC1006 threads. On X.400 directory replication bridgehead servers and dedicated public folder servers that handle a large number of connections, it is recommended that this value be modified from its default of 2 to a value of 10.
