A DNS server is required in the AD domain to resolve the computer name in the domain. But how does the calculation in the domain resolve the domain name of the public network? Of course, one way is to add a public DNS server to each computer in the domain; the other easier way is to add a Forwarder on the domain DNS server ).

The demo environment uses Windows 2008. Two Computers are in the same domain, one is a DNS server, and the other is a computer for other purposes. The following shows how to set up a DNS server, so that another computer can resolve the Internet domain name (on the Internet ).

 

For example, the IP address of the DNS server is the loopback address.

 

In the IP settings of another computer, DNS points to the DNS server in the domain. In addition, if you want to access the Internet, you must set the default gateway.

 

Open DNS Manager

 

Add a Forwarder. Here the Alibaba public DNS server is used.

 

In this way, all computers in the domain can resolve the public network domain name.

 

Summary: If you want to access the public network, set the default network management for the computer, and set Forwarder for the domain DNS server.

Cannot a computer in the AD domain be configured with a public DNS?

First, the internal DNS server is only responsible for internal resolution and forwarding.
Second, you should enter the DNS server address for the internal Client. Otherwise, what will be the purpose of creating a dns server?
Of course, you can configure the public network DNS address on the Client side, but in this way, the internal DNS server function is useless.
Then: Yes, sometimes the Client cannot find the AD, and the connection will fail, prompting that the connection is unavailable.
You should check the settings of your DNS server to see if it can be resolved properly.

What are the DNS server resolutions of subsidiaries? Internal domain names are resolved using AD-integrated DNS, while external domain names are resolved using local DNS?

It seems that this problem is very simple. Is it wrong?

Intranet DNS sets up DNS servers of their subsidiaries,
Internet, you only need to set a forwarder on the DNS server to point to the ISP.
