Troubleshooting Tip: DNS server is not resolving certain domains when DNS database is configured

[Nivedha]

Description	This article describes the issue when the DNS server is not resolving certain domains when the DNS database is configured.
Scope	FortiGate.
Solution	To configure the DNS database, refer to this document: FortiGate DNS server. In this example, the DNS database is configured as follows: Answer records are as follows: 1.test.com resolves to 13.14.15.16. 2.test.com resolves to 13.14.15.17. Since authoritative is enabled, this means that FortiGate's DNS database has all records for test.com. Anything other than 1.test.com or 2.test.com will not be resolved in this case. If encountering such an issue, it is necessary to disable the authoritative on the FortiGate DNS database as it does not hold all records for the domain test.com.
