SUMMARY
This article outlines the procedure to successfully install an Exchange Server version 5.5 service pack on a computer running clustering services.



MORE INFORMATION
To install an Exchange Server version 5.5 service pack on a computer running clustering services:
 * 1) Install the service pack on the primary (active) node by using the Update.exe program from the Exchange Server 5.5 service pack CD-ROM.

IMPORTANT: Do not failover (move) the Exchange Server group to the secondary node.
 * 1) Install the service pack on the secondary node by using the Update.exe program from the Exchange Server 5.5 service pack CD-ROM.

NOTE: If you update an earlier version of Exchange Server on clustered computers, the installation program stops the Exchange Server services. When the update installation is finished, the installation program restarts the services. This causes an interruption for users, because they cannot connect to the server during this time.
