Clustering in different versions of Server 2003

It's my understanding that the standard version of server 2003 can do a 2 node cluster, but you need to go up to Enterprise for more than a 2 node.  Is that correct or am I mistaken?

Also, do I need to go to the Enterprise version of Exchange 2003 in order to do any clustering at all?

You can do a network load balancing cluster with Standard Server.  You CANNOT cluster Exchange without Enterprise or Data Center versions.  Further, you need Exchange Enterprise licenses to cluster exchange

Man... I spent forever trying to find a product comparison like that... thanks for the link.

What's the difference between Load Balancing Clusters and Server clusters (assuming there is something less obvious than the name).

Server clusters essentially result in one server remaining idle while the other does all the work - in the event that one fails, the idle server takes over - a "fail-over cluster"

A load balanced cluster is generally trying to spread the requests for information over two systems - this is generally done with IIS.
