2. Type REG ADD \\DemotedDC\HKLM\SYSTEM\CurrentControlSet\Services\Eventlog /V Start /T REG_DWORD /F /D 4 and press Enter, where DemotedDC is the NetBIOS computer name of the demoted domain controller.

3. Use PsShutdown.exe to restart DemotedDC.

NOTE: Ignore any error messages about service failures.

4. Open a CMD.EXE Window.

5. Type the following commands, pressing Enter after each line:

del /q /f %SystemRoot%\System32\Config\DnsEvent.Evt
del /q /f %SystemRoot%\System32\Config\NTDS.Evt
del /q /f %SystemRoot%\System32\Config\NtFrs.Evt
REG DELETE "\\DemotedDC\HKLM\SYSTEM\CurrentControlSet\Services\Eventlog\Directory Service" /F
REG DELETE "\\DemotedDC\HKLM\SYSTEM\CurrentControlSet\Services\Eventlog\DNS Server" /F
REG DELETE "\\DemotedDC\HKLM\SYSTEM\CurrentControlSet\Services\Eventlog\File Replication Service" /F
