Monitors Recursive Query Failure/sec
This monitor evaluates the performance counter Recursive Query Failure/sec of DNS object. If the average value of the counter is above the configured threshold for more than the configured number of samples, it changes state.
Frequency: The number of seconds between performance counter samples.
Threshold: The value at which to alert.
Num Samples: The number of samples over which the average is taken.
The DNS server is misconfigured or a large number of requests are being made to it that is cannot satisfy.
Ensure that the DNS server is hosting the correct zones and forwarders, and that the clients are making requests of it that it should be able to answer.
