I'm not sure what identity DNS is, but the first step to troubleshoot DNS is to use nslookup to check results from the DNS server provides and what it uses as a resolver

To troubleshoot DNS issues for a website on Micro Focus DNS, you can follow these steps:

1. Check if the DNS server is running properly: Ensure that the Micro Focus DNS server is running and there are no errors in the logs.

2. Verify DNS records: Check if the DNS records for the website are correct and up-to-date. You can use the nslookup or dig command to query the DNS server for the website's DNS records.

3. Check for network connectivity issues: Make sure that there are no network connectivity issues between the client and the DNS server. You can use the ping command to check the connectivity.

4. Check DNS cache: If the DNS server has cached the old DNS records, you need to flush the DNS cache to retrieve the latest DNS records. You can use the ipconfig /flushdns command to flush the DNS cache on Windows.

5. Test DNS resolution: Test the DNS resolution by accessing the website from different devices and networks. If the website is not accessible, the DNS server may not be able to resolve the domain name to an IP address.

6. Check firewall settings: If there is a firewall in place, make sure that it is not blocking DNS traffic. You can temporarily disable the firewall to check if it is causing the issue.

7. Seek technical support: If you are unable to resolve the DNS issue, seek technical support from Micro Focus or a qualified DNS expert. They can help you diagnose the issue and provide a solution.
