DNS Request time out issue windows server 2019

Question

Hi i have 2 domain controllers in my network ( 2 physical windows server ) and they replicate each other, every other day i got this DNS issue with resolving addresses and websites and when i use nslookup i got this error ( image attached ) Knowing that I am using server 1 IP as Preferred DNS server IP for server 2 and and server 2 IP as Alternative DNS server for itself and vice versa, i tried all possible solutions and nothing work but restarting the physical servers, what should i do??? Kind regards

Answer 1

Hi

If you’re using domain controllers as DNS resolvers, you can check if they are able to resolve external DNS records by running the following command:

nslookup
server IP1
google.com

If the DNS server is not responding , check if you have already configured DNS forwarders on each dns server to forward DNS requests for external DNS name to external DNS server like 8.8.8.8 if the DNS forwarders is well configured, if should be network flow issues.

Hello, From the picture, it seem that the computer is not connected to the DNS server. Please ensure that you have properly configured some parameters for your DNS server and network adapter.
