Upgrading the Cluster Host

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

After you ensure that no clients are accessing the cluster host, upgrade the cluster host to Windows Server 2003. Ensure that during the upgrade process you apply the latest service packs and hotfixes.

After the upgrade is complete, check the upgrade logs (Setuperr.log in the windir folder of the system volume) to identify any problems that occurred during the upgrade process. Many applications and services running on the cluster have log files that identify problems that occur during the upgrade process. For example, IIS 6.0 creates a separate log that documents the upgrade process for IIS components. Make certain that you review any upgrade logs for the applications and services running on the cluster.

For more information about these upgrade logs, see "Additional Resources for Deploying Network Load Balancing" later in this chapter.
