MORE INFORMATION
If you upgrade an existing Exchange 2000 cluster node to Exchange 2000 SP1, consider using the following procedure:
 * 1) Manually move the Exchange 2000 virtual server to another node.
 * 2) Upgrade the node to Exchange 2000 SP1.
 * 3) Manually fail back the Exchange 2000 virtual server.

This procedure provides users access to Exchange on another node during the upgrade. To reduce the chance of errors, upgrade one node at a time, instead of upgrading all nodes simultaneously.
