Active/Active SQL Cluster

I have two new SQL 2000 instances on separate Win2K3 servers. Is there a way within W2K3 to set them up as an active/active cluster. And do I need to set it up just one one server(insert cd and it will recognize the other server to connect.
We cannot take standalone Win2K3 servers and form a cluster. We need to have a Certfied Cluster Solution listed in Microsoft Hardware Compatibility List (HCL).
A certified cluster does not consist simply of parts that individually reside on the Microsoft Hardware Compatibility List (HCL).
For example, suppose Server model S, HBA model H, storage frame F, and fibre switch W are all certified with Microsoft. This does not mean that a cluster built with S+H+F+W is supported - and customers
requiring support should not simply build a solution with these components.
Non-certified cluster solutions are not guaranteed to operate correctly. For example, the shared disks may be visible to multiple nodes and this can lead to corruption of application data or instability where the
connection to the disks is not reliable. You can waste a lot of time by attempting to troubleshoot perceived server cluster issues that are being caused by the cluster hardware that you are using.

NOTE: If the cluster solution is not listed on the HCL or WSC in the Cluster category, the cluster solution is considered UNSUPPORTED. However, Microsoft PSS will offer troubleshooting tips if the customer
requests them. PSS does NOT guarantee that a resolution will be found for non-HCL or non-WSC Clusters. If no resolution is found, the incident is not refunded.

|||With 2000. the right terminology is single or multi instance.
Active/Active terminology doesnot apply to SQL 2000.
Yes it is possible.
