05 set up an extra domain controller on Windows Server 2008R2

Setting up an extra domain controller on top of Windows Server 2008R2 is much easier than building a second DC, but there are a few nuances to pay attention to

Demonstration prerequisites:

1. Configure IP address, DNS

two。 Turn off the firewall

3. Test connectivity

Create a new DNS forward lookup zone for additional DC above the root DC

Select "main area"

Domain name for additional DC: leo.com

Select "allow non-secure and secure dynamic updates" here

View the added DNS record information

Configure the AD wizard to work on the server where you are going to build additional DC

Install AD

Note that you select "existing forest" here, and then "add domain controllers to the existing domain"

Enter the domain name of the root DC and the login credential information of the root DC

It should be noted here that the root DC is selected here, and take a look at the tag × × ×. What is built here is the extra domain controller.

Click "Yes" directly below.

Reductive password for additional DC

You also need to pay attention to this place. It is also easy to report errors. If the building is not successful, you still need to re-build the DC, and then build the additional DC, so the success rate is relatively high.

Two DC servers, one primary and one standby (additional)

Verify the data synchronization relationship between the additional DC and the primary DC

Create a new user on the additional DC

Check on the main DC and find that it is synchronized immediately. This is the end of the demonstration of establishing an extra domain controller on the Windows Server 2008R2.
