The function and creation of additional domain controller in Win7 system

Win7 How does the system create an additional domain controller? What does it do? The following simple steps teach you how to create.

The role of the additional controller: the so-called additional controller, is a domain controller other than the first domain controller.

When you install multiple domain controllers in the same domain, you have the following benefits:

1. Improve the efficiency of user login. Because multiple domain controllers can share the work of auditing users at the same time, you can speed up the user's logon speed. When the number of users in the network, or a variety of network services need to authenticate, should install more than one foreign controller.

2. Provide fault-tolerant function. Even if one of the domain controllers fails, it can still be serviced by other domain controllers, allowing users to log on normally and provide user authentication.

3. You do not need to back up the Active Directory. When there are more than one domain controller (dc,domain Controller) in the domain, the domain controllers can replicate and backup with each other. Therefore, when you reinstall one of the DCs, backup Active Directory is not required, just remove it from the domain, reinstall it, and bring it back into the domain, and the other DCs will automatically replicate the data to this DC. That is, if only one or more of the last DC is left in a domain, it is necessary and must be backed up for Active Directory.

4. When installing additional domain controllers, it is necessary to replicate the Active Directory database from an existing domain controller to this new domain controller.

To create a method/step:

1. Execute win7 System "start" 丨 "Administrative Tools" 丨 Server Manager command, in the Server Manager window, click the console tree 丨 role option on the left, click the Active Directory Domain service button on the right, and then click Active The Directory Domain Services Installation Wizard (dcpromo. exe) button launches the Setup wizard and clicks the Next button continuously.

2. Until the dialog shown appears, click to select the existing forest to add a domain controller to an existing domain button, and then click the Next button.

3. In the dialog box, the account credentials for the installation are performed (This example uses Domain Admins LCHH), and then click the OK button to continue clicking the Next button.

4. Set the source of the domain data in the dialog box (this example uses the default copy data from an existing domain controller through the network), and it is recommended that you do not change it, and then refer to the method of installing the child domain, after the computer restarts, and the additional domain controller configuration is complete.

Summary: Learn what the extra controller does, learn how to install additional controllers, and make your network proactive.
