Authentication of computers and users into the network. Here's what the role of installing additional domain controllers is.

1. Improve the efficiency of user login. Because multiple domain controllers can share the task of auditing users at the same time, user logins can be accelerated. When there are a large number of users in the network, or multiple network services need to be buried for identity authentication, multiple extra-domain controllers should be installed.

2. Provide fault tolerance function. Even if one of the domain controllers fails, the other domain controllers can still provide services for users to log in and provide user authentication.

3. No backup is required.

Therefore, when you reinstall one of the DCs, it is not necessary to back up the Active Directory, just remove it from the domain, reinstall it, and put it back in the domain, and the other DCs will automatically copy the data to this DC.

That is, if there is only one or only one last DC left in a domain, it is necessary and necessary to take a backup of Active Directory.
