DescriptionThis computer must be configured as a domain controller. To prevent this computer from shutting down in the future, run Setup on the disk that you used to install the operating system to configure the computer as a domain controller.
Event InformationCause:
This issue can occur if the Windows 2003 Small Business Server integrated setup was not completed. Windows 2003 Small Business Server must be a domain controller and hold all FSMO roles for the domain. In order to facilitate migration from an existing domain, the Small Business Server can function for 7 days after installing without being promoted to a domain controller. After that time, the Small Business Server must be promoted to a domain controller using the integrated setup. If the integrated setup is not completed, the SBCore service will initiate a shut down of the server. 
Resolution:
To resolve this issue, complete the Windows 2003 Small Business Server integrated setup. To access integrated setup, select "Windows Small Business Server 2003" in the Add/Remove Programs applet in the Control Panel.
