1. I will not talk about Installation
2. Modify the network attribute of the DC and set the primary DNS as the IP address of the DNS server used by the domain controller, which is usually the same as that of the DC. The following assumptions are also made.
3. Under the domain corresponding to the DNS server, create the record corresponding to the PC to be added (think about the record in domain name management). The content is the PC name (for example: Cust) and the IP address of the PC. Corresponding to the second-level domain name and IP address in the domain name management. Restart the server.
4. Set the primary DNS of the PC to the IP address of the DNS server used by the domain controller.
5. In the control panel, system properties, and computer name of the PC to be added, press the change button to modify the corresponding PC name on DNS, the domain name is the domain corresponding to the current DC.
6. Create a corresponding user on the DC, and then log on to the PC using the user as a domain.
Note: The following ports on the DC must be opened to avoid being blocked by the firewall.
88 TCP UDP
445 TCP UDP
389 TCP
137 138 UDP
139 TCP
However, it seems that these ports are not open enough in the experiment. It seems that only Windows Firewall is opened first. I don't know if anyone knows how to complete these ports!
