Tests each IP address the server is bound to
A DNS server can be bound to listen on multiple IP addresses. This monitor tests each individual IP address for the PTR record 127.0.0.1 which should succeed regardless of whether or not the server has any zones and/or forwarders configured.
Interval Seconds: The interval at which this monitor performs a NSLOOKUP.
Script Timeout Seconds: The total time SCOM will allow the script to run before terminating it.
Query Timeout Seconds: Used for the -timeout option of NSLOOKUP.
Query Type: Used for the -querytype option of NSLOOKUP. Acceptable values are: A, CNAME, PTR, NS, or SOA.
Host Name: The host record to be resolved by NSLOOKUP.
Server: The server to which NSLOOKUP should direct the query.
Accept Non Authoritative: Whether or not SCOM should accept a Non-authoritative response to NSLOOKUP.
NSLOOKUP failed to resolve 127.0.0.1
Ensure that the DNS server is started and bound to listen on all IP addresses or the IP address that this monitor is targeting.
