Have not worked on DNS for long time and have questions hope some one will help me on. DNS is slow response in my client place. The DNS is running on DC , it is active directory integrated . I think it is the good practice.
This DNS is set to forward the queries to their isp , i think it is best practice not to expose the dns to public.
Are the above settings correct ?
2- nslookup on one of the dns timing out error , What could be the issue?
