Message:	Multiple domain controllers running Windows Server 2003 for Small Business Server have been detected in your domain. To prevent this computer from shutting down in the future, you must remove all but one of these from the domain.

Explanation
In a Windows Small Business Server 2003 domain, only one computer can run Windows Small Business Server unless you are in the process of migrating from an earlier version of Small Business Server. If you are migrating, you have 7 days to complete the migration and remove the earlier version of Small Business Server. This caveat does not apply to domain controllers that are running Microsoft Windows Server 2000 or Windows Server 2003 operating systems.

User Action
Ensure that only one computer in the domain is running Windows Small Business Server. For more information about migrating from an earlier version of Windows Small Business Server, see the article “Migrating from Small Business Server 2000 or Windows 2000 Server to Windows Small Business Server 2003” at the Microsoft Web site.
