Thanks everybody for helpful discussions on this forum.

We have two sun java system 6.1 webservers. We are in the process of using one as failover to another. The second one also serves as a load balancer. When do we require a load balancer (h/w or s/w) .. Could anyone also comment on DNS roundrobin method ... is it dependable and trustworthy? For what pourposes/websites can it be used?

Thanks again.
