This article is not supporting the use of unlicensed software. It assumes you have a legitimate new installation of Microsoft Windows Server 2003 for SBS and have not yet completed the installation to commit the machine as a domain controller but are experiencing the machine shutting down after 60 minutes.
The Microsoft Windows Server 2003 SBS EULA reboot occurs because a newly built machine has not yet been made a primary domain controller as per the Windows Server 2003 SBS EULA. The following work around prevents the reboot and 'creates more time' to decide on the final role of the server.
1. Manually kill the 'sbscrexe.exe' process in task manager.
2. Run regedt32 (not regedit) and locate the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SBCore
3. Right click the key, select permissions and add 'SERVER\Administrators' for 'Full Control'
4. Apply and enforce new permissions to all key siblings then refresh the registry view.
5. Locate the following object (now visible where previouly hidden): HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SBCore\Start and change from 0x02 to 0x04.
6. If access is denied remove and create a new DWORD=0x02 object called 'Start'
7. Reboot computer and confirm that the service SBCore Service is disabled and not running.
8. Done.
You now have as much time as you need to decide on the domain control role of the Microsoft Windows Server 2003 SBS. Once you have completed the the final steps in making your server a domain controller simply set the SBCore Service back to Automatic through the normal services menus.
