The Diagnostic Policy Service (DPS) Configure Scenario Execution Level machine setting should be configured correctly for Fault Tolerant Heap . Determines the execution level for Diagnostic Policy Service (DPS) scenarios. If you enable this policy setting, you must select an execution level from the dropdown menu. If you select problem detection and troubleshooting only, the DPS will detect problems and attempt to determine their root causes. These root causes will be logged to the event log when detected, but no corrective action will be taken. If you select detection, troubleshooting and resolution, the DPS will attempt to automatically fix problems it detects or indicate to the user that assisted resolution is available. If you disable this policy setting, Windows will not be able to detect, troubleshoot or resolve any problems that are handled by the DPS. If you do not configure this policy setting, the DPS will enable all scenarios for resolution by default, unless you configure separate scenario-specific policy settings. This policy setting takes precedence over any scenario-specific policy settings when it is enabled or disabled. Scenario-specific settings only take effect if this policy is not configured. No reboots or service restarts are required for this policy to take effect: changes take effect immediately. This policy setting will only take effect when the Diagnostic Policy Service is in the running state. When the service is stopped or disabled, diagnostic scenarios will not be executed. The DPS can be configured with the Services snap-in to the Microsoft Management Console.
