Installing an Exchange Service Pack

Installing service packs is very important for keeping a secure, well-run system. This procedure needs to be followed both for servers running Exchange and any machines loaded with the Exchange administration tools. When applying any service pack, you may be prompted to install some other hot fix or service pack first for the operating system. For example, when installing Exchange SP1 on Windows Server 2003, you must also have the hot fix from MS KB 831464.

Using a graphical user interface

  1. Download the latest service pack from Microsoft. This can be found at The current Exchange service pack at the time of this writing for Exchange 2003 is Service Pack 1.
  2. On the Start menu, click Run, type the path to the service pack executable (e.g., E3SP1ENG.exe), and click OK.
  3. When asked for a folder to extract the files to, type C:\Temp\Exchange2003 and click OK.
  4. On the Extraction Complete screen, click OK.
  5. On the Start menu, click Run, type the full path to update.exe, and click OK. This will vary by service pack and language version, but here is an example path: C:\Temp\Exchange2003\E3SP1ENG\setup\i386\update.exe.
  6. On the Welcome screen, click Next.
  7. On the License Agreement screen, read through the agreement and if you agree, click I agree and click Next.
  8. On the Component Selection screen in the Action column, verify that the action specified is Update and click Next. If an operating system update is required first, you will get a pop-up explaining what needs to be done.
  9. On the Installation Summary screen, verify actions and click Next.
  10. On the Completing the Microsoft Exchange Wizard screen, click Finish.

Using a command-line interface
Service Pack installations can be handled through unattended installations just like regular Exchange server installations. You will need to generate and use the appropriate unattended installation INI file.

Once you have an unattended file, use the following command to update.

:\<path_to_sp_files>\update.exe /unattendfile <unattendfile>

Note that if there is an error during the installation process, it will be recorded in the Exchange Server setup log, which by default will be located in the root of the system drive, generally c:\.
