This wizard configures high availability for a service or application. After you successfully complete this wizard, if a clustered server fails while running the service or application, another clustered server automatically resumes the service or application (a process known as failover). If the service or application itself fails, it can be automatically restarted, either on the same server or on another server in the cluster, depending on options that you specify.  If you want to cluster a complex application such as a mail server or database application, see that application's documentation for information about the correct way to install it.
