I’m having some problem with ip address for the module 2:active directory & identity with windows server when I type nslookup ad.serveracademy.com for the second domain controller i’ve been getting dns request time out and I don’t know what’s wrong. The second picture is the ip for the second domain controller. The first domain controller has 10.1.0.10
In the end, it resolved the IP addresses for the domain controllers.
Perform an ipconfig /flushdns and try to resolve for SADC01, what do you get?
