Newb question regarding cluster load balancing

Hello to all,
I am currently working on creating a Windows 2003 server cluster (3 nodes)
with the intent that it serve our web app which requires multiple SQL
databases. The question I have is this: How can I configure load balancing
for this? It seems that clustering services only allows 1 of the nodes to
access the DB at any given time (which is logical). If this is true, how
will I be able to leverage the processing power of the other two nodes if
they are idle while the node that is hosting the DB does all the work?
Any help would be appreciated.

You can install multiple instances of SQL Server on a failover cluster. You
cannot natively load-balance the workload between these multiple instances.
They act as independent SQL servers. SQL Clustering is a failover
technology and does not natively load balance.

|||Thanks Geoff for the information. I thought as much but hoped otherwise.
