I am extremly new to clustering services. I am wanting to deploy two new identical servers and attach them to a NAS with gigabit ethernet. I just want to mirror the applications that run on these servers. That way if server1 fails, server2 can take over with the apps. Is that possible or does it require the software to be written for clustering? I know exchange and sql have it. Well any info would be greatly appreciated because i am a lil confused right now. Thanks in advance.

cluster failover ?

A cluster, in the MSCS sense, uses shared SCSI storage or emulated SCSI over Fibre Channel. NAS isn't going to work for the shared storage.
Given an MSCS cluster, You can either go with an application that is cluster-aware, such as Exchange or SQL, or configure the application as a generic cluster resource. The second route can get complex depending on the application, or may not be possible at all; it all depends on the application.
Another route to go is Network Load Balancing. This works well for network applications, but there is no shared storage. Each node contains all the files, and if any synchronization is required you have to do it.
