The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine what version of DomainPrep was last run in the given domain. The version number of DomainPrep acts as the Exchange signature for the domain. The Exchange Server Analyzer examines the objectVersion attribute of the given domain's Exchange System Objects object. There are two valid integers:

If the Exchange Server Analyzer does not find one of the above values for the objectVersion attribute, an error is displayed.

This value is likely to be incorrect if you installed a pre-release version of Exchange 2000 Server or Exchange Server 2003 in the given domain, but did not run the released version of DomainPrep.

In Microsoft Exchange 2000 Server and Exchange Server 2003, you performed the Active Directory preparation steps by running setup /forestprep and setup /domainprep. Exchange 2007 does not have the /forestprep and /domainprep options. For Exchange Server 2007, you run the setup /PrepareDomain process, or the Setup Wizard, with an account that has the permissions required to prepare Active Directory and the domain.

To remedy this error for Exchange 2000 Server or Exchange Server 2003, run the final released version of Exchange 2000 Server DomainPrep, Exchange Server 2003 DomainPrep, or the final released version of the PrepareDomain process or Setup Wizard for Exchange Server 2007. The account you use to run DomainPrep, PrepareDomain, or the Setup Wizard must be a member of the Domain Admins security group in the local domain and a local computer administrator.

To run DomainPrep for Exchange 2000 Server or Exchange Server 2003

  1. Insert the Exchange CD into your CD-ROM drive. You can run DomainPrep on any computer in the domain.

  2. At a command prompt, type <drive>:\setup\i386\setup /DomainPrep, where <drive> is your CD-ROM drive.

  3. On the Welcome to the Microsoft Exchange Installation Wizard page, click Next.

  4. On the License Agreement page, read the agreement. If you agree to the terms, click I agree, and then click Next.

  5. On the Product Identification page, type your 25-digit product key, and then click Next.

  6. On the Component Selection page, ensure that Action is set to DomainPrep. If not, click the drop-down arrow, and then click DomainPrep. Click Next.

  7. On the Completing the Microsoft Exchange Wizard page, click Finish.
