Why should we install extra DC? What should I pay attention to when installing additional DC? How do I install additional DC? What if I want to uninstall additional DC? What do you need to pay attention to when uninstalling? Please let me answer these questions one by one.

First, the benefits of installing additional DC:

1. Provide fault tolerance. When a DC fails, we can still continue to provide services by other DC to make our work work normally.

2. Provide load balancing. Multiple DC can share the user audit work at the same time to speed up the audit speed.

3, it is easier for users to connect and access. If the branch needs to connect to the DC of the headquarters, but when the network speed is slow and the login time is long, you can install additional DC in the branch to reduce the branch login time and improve work efficiency.

Second, what should you pay attention to when installing additional DC:

1, the operating system must support the current domain functional level. If the domain level is server 2008, the system with additional DC must be server 2008 and later.

2, the installer must have domain administrator privileges.

3The configuration of the IP address and DNS is correct. (DNS usually points to the first DC)

4. Ensure network connectivity.

Third, the experimental steps:

1. Preferred DNS points to the main DC

2, running dcpromo on a stand-alone server

3. Select the advanced mode and click next.

4, choose to install to an existing domain

5. Enter the domain name of the main DC, and click next to enter the DC administrator and password

, 6, the rest of the options are available by default

Fourth, matters needing attention to uninstall DC.

1, if there are other domain controllers in the domain, the domain controller is demoted to a member controller.

2, if the domain controller is the last domain controller in the domain, the domain controller is demoted to a stand-alone server.

3, if the domain controller plays the Global Catalog role, make sure that there are other domain controllers in the Global Catalog role before uninstalling, otherwise it will affect the user's login operation.

4. You can't shut down or disconnect the network directly. You need to use the dcpromo command to uninstall it.

Fifth, the method of unloading the domain controller.

1. Log in to the domain controller using administrator. Enter "dcpromo" in the run

2, select whether to delete or not in the Delete Domain interface.

3. Enter a password in the "administrator password" interface, which you need to use when logging in to this computer.

4. Uninstall the domain controller and restart it after completion.
