The Startup and permission should be "Not Defined" and Source GPO should be Blank
5. Check Startup, Permission and Source GPO for COM+ Event System and COM+ System Application. The Startup and Permission should be "Not Defined", Source GPO should be Blank for these services as well.
Note : The SMC service is dependant on COM+ and System event notification services, these services should not have any permission issues. Withdraw any group policy from these services and make it Not defined. In addition, withdraw Default Domain Policy from these services.
