Build an Exchange 2003 Cluster: Install Exchange on the Cluster

Installing Exchange 2003 SP2
After you've successfully created an EVS that uses Exchange 2003 RTM, I advise you to upgrade the cluster to Exchange 2003 SP2. Before you upgrade your cluster to Exchange 2003, be sure to upgrade any front-end servers to Exchange 2003 SP2. You must apply service packs to front-end servers before you can upgrade back-end servers. For Exchange 2003, Microsoft introduced a new procedure for upgrading Exchange service packs. To learn more about this procedure, see "Exchange 2003 Clusters: Rolling Upgrades," July 2005, InstantDoc ID 46335.

To install Exchange 2003 SP2, log on to Node 1 (it should be passive now because you've just performed a failover to Node 2) and apply Exchange 2003 SP2 by running update.exe (located in the \setup\i386 folder of the Exchange 2003 SP2 CD-ROM). At the Licensing Agreement screen, select I Agree to accept the License Agreement and click Next. Under the Action column, select Update, as Figure 4 shows. Select the default action (which is to update all components, such as ESM). Be aware that when the update procedure is done, you might be prompted to reboot. I was prompted to reboot because I performed the installation over a Remote Desktop connection. . . .
