Windows domain controller root domain name settings

Ordinary people may not think carefully about what the root domain name of the windows domain controller is set to, but for people with obsessive-compulsive disorder, they must figure it out before they can do it.

This is a question that has been bothering me for a long time, and there are two entanglement points:

First, do you need to set a real domain name?

Second, does DNS point to the DNS of the school, or is it a DNS service built with windows?

After thinking about it carefully today, I suddenly realized it.

According to Microsoft, the number of PC in a company's network is less than 10. Workgroup mode is recommended, and domain management mode is recommended for more than 10.

First, this network may be a private network, private network, there is no DNS resolution server, so this domain name does not need to be real.

Second, it is OK for DNS to be placed on the school's DNS parsing server, as long as dns has a hot backup or cluster. Personally, I think it is safer to build a DNS service on the domain controller, but it will be worse anyway. In addition, we make at least two domain controllers, one of which is broken will not affect the normal use of domain users.
