Issues with Windows Server 2008
Attempting to join a new Windows Server 2008 machine to the network triggers this warning... The message indicates DNS resolution issues within the domain. Ensure the client is properly set up to connect to a DNS server that supports resolving names in the target domain. You’re able to access the internet from Windows 7/8/10 but not from the Server 2008 machine—this could point to configuration or network restrictions. Since you’re now connected to a Windows Server 2012 R2 DC, check firewall rules, DNS settings, and ensure the server is reachable on the internal network.
Choose between adding as a DC or as a client. Enter the IP of the 2012 R2 device into the DNS settings. When prompted, select "Use the following DNS server address." Also, configure a static IP for the server.
Additionally, the domain name matters—use the exact case. Also, test the DC server connection.
I suspect there might be an issue with your DNS server. I checked the information online.
Have you confirmed the DNS role is set up on the DC? Visit the server and verify its presence.
