Aggregates the state of all IP Addresses the server listens on. Alerts are generated at the individual IP Address.
This is a “Worst Of” monitor. It will show as unhealthy if any of the server’s listening IP addresses are unresponsive to NSLOOKUP.
One or more of the IP addresses the DNS server is configured to listen on did not properly respond to NSLOOKUP.
Verify that the server’s network configurations are correct. Verify that the DNS server is configured to listen on the correct IP addresses. Verify that no firewall software is interfering with DNS.
