Creating additional domain controllers with media

I talked to you earlier. Create an additional domain controller using network replication, but you may encounter a problem in your enterprise's time application:

For example: Beijing has a contoso.com primary domain controller, which now needs to create an additional domain controller in Shanghai, but the network latency between Beijing and Shanghai is large, and normal data replication is unsuccessful. What should we do with this situation?

Solution: Create an ad Database media file in Beijing that holds the data in the AD database. Copy this media file to the Shanghai server and use the media file in Shanghai to create additional domain controls.

The following is a detailed experiment to illustrate the use of media files to create additional pre-control methods:

Experiment Preparation:

1. Two Windows Server servers Server01 and server03.

2. Two servers connected to the network

3, two servers have a storage disk other than the C drive.

Note: Media files cannot be stored on the C drive.

OK, with the above preparation we begin to experiment:

First promote the SERVER01 to a domain controller:

To open Server01 Server Manager:

Mouse click Management:

Click Add Roles and Features:

Click Next:

Tick the role-and feature-based installation and click Next:

Tick Select a server from the server pool and click Next:

Here we tick Active Directory Domain Services:

Click Add Features:

Click Next:

Click Next:

Click Next:

Click Install:

To start the installation, we wait for it to complete:

When the installation is complete, click Close; Notice that at this point the Server Manager has a triangle at the top right, as shown below:

Click on the triangle number:

Click Promote the secondary server to a domain controller:

Note Here we tick add a new forest, and enter the root domain name, here I use contoso.com, click Next:

Note Here to check the domain Name System (DNS) server and enter the password for the directory Restore mode, click Next:

Here you can see the location I have selected the system gave us a bug, because we did not install DNS server, we directly next system will automatically create a DNS server for us, here I directly click Next:

Here the system for us to create a NetBIOS domain name, this domain is used for some old-fashioned machine, here I directly click Next:

Here the system gives us the directories stored in the installation files, where I keep the default, click Next:

Here the system gives us some brief information to install, we confirm the error click Next:

Prerequisites Check the car through, we click Install to upgrade the domain control:

The installation begins and we wait for the installation to finish:

When the installation is complete, the system restarts the computer automatically, and we wait for it to start to complete:

Reboot is complete and you can see that we are logged into the domain.

Here we start to create the contoso.com media file:

Press the WIN+R key at the same time:

Enter cmd, and then tap enter:

Enter Active Directory Maintenance tool command: Ntdsutil, hit ENTER:

Enter the activation instance command below: Activate Instance NTDS, hit ENTER:

Enter IFM:

Enter create full backup address, here I back up to E drive so I input: Create full E:\IFM, hit ENTER:

OK, here Our media file is created successfully.

Below we will use the media to promote SERVER03 to an additional domain controller:

First we use some way to copy the already created media to the local disk:

Let's start by increasing the additional domain control

To open SERVER03 Server Manager:

Mouse click Management:

Click Add Roles and Features:

Click Next:

Tick the role-and feature-based installation and click Next:

Tick Select a server from the server pool and click Next:

Here we tick Active Directory Domain Services:

Click Add Features:

Click Next:

Click Next:

Click Next:

Click Install:

To start the installation, we wait for it to complete:

When the installation is complete, click Close; Notice that there is a triangle at the top right of the Server Manager, as shown below:

Click on the triangle number:

Click Promote the secondary server to a domain controller:

Note Here tick add domain controller to an existing domain, and enter the domain name of the domain we want to join in the specified action, then click Change:

Enter user name and password click OK:

Confirm that the three messages selected in the image above are correct and click Next:

Enter the directory Restore Mode password and click Next:

Click Next:

Note here choose to install from the media, and then find the directory where the media, as shown below:

Click Next:

Here the system gives us the directories stored in the installation files, where I keep the default, click Next:
