DNS conflict

Question

Am installing and configuring Windows Server 2022 for a client with AD DC. The network IP is static from the ISP (Spectrum) using "Port Forwarding and IP Reservations" at the Spectrum router. The AC DC domain name matches a www out on the Internet. When I do nslookup domain name at the server it resolves to the AD DC address with the server's 192 IP. However, at a workstation, nslookup resolves to the Internet websit IP address with the same domain name, but with www. For this reason, workstations cannot join the domain. I have tried managing DNS settings, but noting works to joing the server domain and access websites via the browser. How do I setup DNS to point the server domain and still get internet websites with the workstation browser?

Hi @CME101

What you need to do is configure the workstation to use one of the domain controllers as a DNS resolver in order to join it to the domain (if the DNS zone of your domain is hosted on the domain controllers) .

In the local DNS server (domain controller), you must add DNS forwarders to let domain controller forward DNS queries to a public DNS server.

If the internal domain has the same suffix as the name of the external DNS zone, the redirection of the DNS requests will not work for this DNS zone, in this case it is necessary to recreate the DNS entries for all your public server like www in the local DNS server.
