EDIT: This post was updated on 5/2/2008 to include links to international versions of new XML files. We're happy to announce the release of the English version of an update to the Exchange Server 2007 SP1 Setup prerequisite check file. This update will allow you to install Exchange 2007 SP1 in a single-label domain (SLD). To read more history behind this, please go here. Localized versions of this file will be available soon, and we'll update this blog post when they are available. Do not use the English version of the file if you are running a non-English version of Exchange 2007. There are three scenarios in which this update can be used: Installation on Internet connected computers:

1. Run Setup (from a file share etc.) and the XML update will be automatically downloaded, installed, and applied. If you are installing from Exchange 2007 SP1 DVD, please see the instructions below.
Installation on non-Internet connected computers:
1. Using an Internet connected computer:
  • Download and extract Exchange 2007 SP1 to a local hard drive.
  • Download and extract the applicable updated ExBPA.PreReqs.xml file listed below. Please note: We suggest that you right-click the link and select "Save target as..." as otherwise the XML file might open in your browser window.
  • Save the file to your local hard drive. Note: Do not make any modifications to ExBPA.PreReqs.xml. Modifying this file will cause it to fail
  • Locate ExBPA.PreReqs.xml which was extracted from the Exchange 2007 SP1 download. The default location is "Setup\ServerRoles\Common\<language>". Rename the original XML file to something else or save it to a different location.
  • Replace the ExBPA.PreReqs.xml file which was extracted from the SP1 download with the updated ExBPA.PreReqs.xml file.
2. Copy the Exchange 2007 SP1 setup files that you have modified to the non-Internet connected Exchange Server which you are trying to upgrade to Exchange 2007 SP1.
3. Run Setup on the non-Internet connected computer by using the files you copied as per above.
If you are installing Exchange 2007 SP1 from the DVD media:
1. Copy the Setup files to the local hard drive. This step is necessary, because if Setup is run from a DVD, it will not check for an updated XML file. This applies to both Internet and non-Internet connected computers. 2. Follow the applicable directions from above, depending on if the computer is connected to the Internet or not.

    Lenny,
    Your understanding is correct.

    In order to perform the domain rename you’d need Windows Server 2003 and Exchange Server 2003.  Windows did not support domain rename until Windows 2003, and if you were to upgrade to Windows Server 2008 you would not be able to install Exchange 2003, which is the only version of Exchange in which you can use the Exchange Domain Rename Fix-up Tool.

    So yes, if you wanted to rename the domain you’d need to install Windows Server 2003 and Exchange Server 2003, and then rename the domain.  At this point however, if you wanted to further upgrade the operating system to Windows Server 2008 you’d need to remove Exchange Server 2003 since Operating System in-place upgrades of Exchange Servers are not supported (see http://msexchangeteam.com/archive/2007/10/04/447188.aspx for more information).

    Your alternative is to build a new FQDN domain parallel to the existing SLD and then migrate users.

    Alex,
    Please wait for the localized versions of the XML file.  I do not have a date on when the localized versions will be available.  As soon as I have more information I’ll post it here

    When do you think will the xml update for other language versions, e.g. German, follow?

    Well,  I think I have the worst case possible.   AD 2000.  Exchange 2000.  Single Domain Label.

    My client wants to migrate AD 2008 with Exchange 2007.

    My understanding is that I can't bypass 2003 version if i want to rename the domain name.   Am I wrong?

    thanks

    How about installing the English Exchange server (with updated ExBPA.PreReqs.xml) on a non-English operating system?

    I still get the error about Single-label Domain Name.

    Well I bit the bullet and it bit back! I tried to install SP1 yesterday and things were going well right up to the point where it failed and will not come back. The current error I get is The domain is invalid. No explanations or anything. I'm wondering if there is something in SP1 that doesn't like the SLD even though it allows the install.

    At this point I'm alomost back up, transport not working. I have a call into MS but I am waiting for a call back this morning. Can't find anything on the web for it.

    It's just a great way to start the week :(

    Thanks for the update

    - I tried to install Exchange 2007 on our single-label domain 1 day too early...

    I was very happy to see this fix the next morning! (We have about 15 users so this was the production-server I was upgrading...)
