The schema master is running Windows 2000 Server
Topic Last Modified: 2009-12-16
Microsoft Exchange Server 2007 and Exchange Server 2010 setup cannot continue because the domain controller assigned the Active Directory directory service schema master role, also known as flexible single master operations (FSMO), is running Microsoft Windows 2000 Server.
Exchange 2007 and Exchange 2010 setup requires that the domain controller that serves as the schema FSMO run Microsoft Windows Server 2003 Service Pack 1 (SP1) or a later version.
The FSMO controls all updates and modifications to the Active Directory schema.
To resolve this issue, do one of the following:
Upgrade the FSMO domain controller to Windows Server 2003 SP1 or a later server version and rerun Microsoft Exchange setup.
Move the FSMO domain controller to a server running Windows Server 2003 SP1 or a later server version and rerun Microsoft Exchange setup.
