KM Server

Important   For security reasons, it is not recommended that you install KM server as part of a cluster.

KM server is a special instance of a clustered Microsoft Exchange Server resource. When installed, KM server is added to the Microsoft Exchange Server cluster group, but the resource is configured not to restart on fail over. For security reasons, you must manually start the KM server service if there is a fail over. You should use the Services application in Control Panel to start the service. After you have started the KM server service, you must bring it online using the Cluster Administrator program. For more information about KM server security requirements, see Microsoft Exchange Server Operations.

Note   KM server is the only service you should start or stop using the Services application in Control Panel.
