Comments
 
This event typically indicates that one of the NTP time servers configured for the time service has failed to answer to queries. This event is common if the time service is using a NTP server DNS name that is configured with a round-robin list of servers (such as pool.ntp.org). Occasionally, one of the servers may experience technical issues so it won't be available for NTP queries.

If the event is persistent, verify the list of servers configured in the time services as upstream NTP servers.
