This article discusses an installation limitation of Microsoft Exchange 2000 Server or Microsoft Exchange Server 2003 in a clustered environment. The installation of an Exchange 2000 or Exchange 2003 front-end server is not supported on a server cluster.
When you configure Exchange 2000 or Exchange 2003 in a front-end and back-end configuration (FE/BE), the Exchange front-end server typically relays Internet client protocol commands to the back-end Exchange mailbox server. A server cluster provides failover capability for Exchange mailbox servers if they are connected to a shared storage location. Because the Exchange front-end server does not store mailbox information, there would typically be only a small benefit to having an Exchange front-end server installed on a server cluster.
To help increase the fault tolerance of Exchange front-end servers, use more than one front-end server, and configure these servers by using a clustering technology such as Network Load Balancing.
