Schema FSMO is Not Windows Server 2003 Service Pack (SP1) or Above
Topic Last Modified: 2006-06-05
The Microsoft® Exchange Server Analyzer Tool checks the Active Directory® directory service forest to learn what server operating system version is running on the Active Directory domain controller schema master. If the Exchange Server Analyzer finds that the Active Directory operations master domain controller, also known as flexible single master operations or FSMO, is not running Microsoft Windows Server™ 2003 Service Pack 1 (SP1) or a later version, the Exchange Server Analyzer displays an error.
The error indicates that Windows Server 2003 SP1 or a later version is required to install Microsoft Exchange Server 2007. Windows Server 2003 SP1 or a later version is required to support new Exchange 2007 permission structures.
If the Active Directory schema FSMO domain controller is not running Windows Server 2003 SP1 or a later version, the Exchange 2007 installation will fail during setup.
This message is a prerequisite check before you deploy Exchange 2007. It is recommended that you have Windows Server 2003 SP1 or a later version running in the forest-wide Active Directory domain controller schema master if you plan to install Exchange 2007.
