Installing Service Pack 1

Microsoft recommends that you apply Service Pack 1 to all servers running Microsoft Exchange Server 5.5 as soon as possible. The Update program installs all QFE patches and basic new functions. Additional new functions are installed separately, as described in the documentation for those functions.

Important  Be sure to make and verify a complete backup of your Microsoft Exchange Server computer before installing this service pack. The service pack cannot be uninstalled.

The system requirements for installing Service Pack 1 are the same as the requirements for installing Microsoft Exchange Server 5.5.

To install Service Pack 1 from the compact disc

1. Make and verify a complete backup of your Microsoft Exchange Server computer.
2. Insert the Service Pack 1 compact disc into the CD-ROM drive.
3. At the Windows NT command prompt, switch to that CD-ROM drive, and then switch to the \<language>\Server\Setup directory (see the root directory for server languages included on this compact disc).
4. Switch to the I386 or Alpha directory (depending on whether you have an Intel or Alpha AXP processor).
5. Type Update, and then follow the instructions displayed on the screen.
