Installation of Exchange 2007 SP2 with Windows 2008 R2 Domain Controllers fails because of outdated Best Practices Analyzer files
When trying to install Exchange 2007 SP2 in a network where all domain controllers are Windows 2008 R2 version, setup fails with following error:
[ERROR] Cannot find at least one domain controller running Windows Server 2003 Service Pack 1 or later in domain 'DC=DCName,DC=com,DC=DCName'. This could be the result of moving domain controller objects in Active Directory. Check that at least one domain controller running Windows Server 2003 Service Pack 1 or later is located in the 'Domain Controllers' organizational unit (OU) and rerun setup.
