Installation of Exchange 2007 SP2 with Windows 2008 R2 Domain Controllers fails because of outdated Best Practices Analyzer files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'.
