The Exchange team has released the July 2004 Microsoft Exchange 2000 Server Post-Service Pack 3 (SP3) Update Rollup to the Download Center.  The KB article for this update is located at  One of the main stories regarding this release is that this update rollup puts a prerequisite on all Exchange 2000 hotfixes being released from this point forward.  In other words, ALL Exchange 2000 hotfixes will now require the update rollup build 6603.1 to be installed before continuing with the hotfix installation.  This was done for a number of reasons.

Besides the official KB article for the rollup, I’ve consolidated the customer FAQs that have come up:

Q: Has the update rollup (6603.1) been released?

A: Yes, the update rollup (6603.1) released August 16.  Get it here.

Q: Who should install this update rollup (6603.1)?

A:  All Exchange 2000 customers with SP3 installed should install the August update rollup (6603.1)

Q: Why did Microsoft release an update rollup for Exchange 2000?

A: The update rollup ensures that all necessary hot fixes are installed and replaces recalled hot fixes.

Q: Why did Microsoft not re-release individual hot fixes that were recalled?

A: An update rollup allows customers to install all previously released hot fixes at once to save time and provide a better overall customer experience.

Q: Does this update rollup supersede "Update Rollup for Exchange 2000 (KB836488)" currently available on the Web?

A: Yes!

Q: Do I need to uninstall the superseded "Update Rollup for Exchange 2000 (KB836488)" before installing this update rollup (6603.1)?

A: No, you can install the (6603.1) update rollup without un-installing the (6556.5) update rollup.

Q: Does this update rollup (6603.1) include all released security fixes?

A: Yes!

Q: Can I uninstall the update rollup (6603.1)?

A: Yes. However, if additional Exchange Server hot fixes are installed after this update rollup, then the hot fixes must be uninstalled in the reverse order that they were installed.

Q: What is the recommended installation procedure for installing both the update rollup and an individual hotfix?

A:             1. Manually shut down Exchange services.

                2. Install the update rollup.

                3. Install the hotfix.

                4. Restart Exchange services.

Q: Does the update rollup require a reboot?

A: A reboot is required only if the installer detects that one or more of the files to be updated are locked open. The hotfix installer makes all attempts to shut down services, close open files, and show files that are in use before continuing with the installation, but if any files remain open, a reboot will be triggered.

Q: Can I install this update rollup using terminal services?

A: Yes, but there are known issues.  For more information, see Microsoft Knowledge Base article 246216, "XADM: Exchange 2000 ExIFS May Not Start after ExIFS Is Manually Stopped", located at 

Q: Does the installer detect 'file in use' while running in silent mode?

A: No. If a file is in use, a reboot is required.

If any other rollup related questions not covered here become FAQs, we’ll be sure to add them to this list.  Thanks and happy update rollup downloading!
