Event InformationAccording to Microsoft:
Explanation:

Notification Services could not update the Skipped Quanta, Skipped Chronicle Rule Firings, Skipped Subscription Rule Firings, and Quanta Behind performance counters. Notification Services will attempt to update the counters at the next quantum interval.
If this error occurs several times, it is likely that the Notification Services performance counters are corrupt and will not be updated until the corruption is resolved. There are several possible reasons for the corruption, including a corrupt entry in the registry and problems in other performance monitor DLLs.
User Action:
If you do not need the Windows Performance counters to be updated you can safely ignore this warning. For the recommended user action and additional information, see Article id 827963.
