Security Log not Update on Server 2003 SP1......after DCPROMO

After applying SP1 (Service Pack 1) to Windows Server 2003, and running Sysprep.exe or Dcpromo.exe on the Windows Server 2003 SP1 computer, SCM cannot log events in the System event log.
This behavior will occur if the logged on console user is not the same user that registered the WMI (Windows Management Instrumentation) repository, or is not registered in the WMI repository.
To resolve this issue use the command:
mofcomp %windir%system32wbemscm.mof
