A Domain Controller (DC) is a critical component of an Active Directory (AD) environment, managing authentication, authorization, and network policy enforcement. Configuring domain controller operations involves optimizing its setup, ensuring high availability, and maintaining its role effectively within a Windows Server domain.
Deploy Active Directory Domain Services (AD DS) and Promote Server to Domain Controller Role.
In this task, you will promote the member server TAILWIND-MBR1 that is already created to a domain controller within the TAILWINDTRADERS domain.
Sign in to TAILWIND-MBR1 as Administrator. In Server Manager, select the Manage menu and then select Add Roles and Features.
On the "Before you begin" page of the Add Roles and Features wizard, click Next.
On the "Select installation type" page, select Role-based or feature-based installation and click Next.
On the "Select destination server" page, choose Select a server from the server pool, ensure TAILWIND-MBR1 is selected and click Next.
On the "Select server roles" page, select the Active Directory Domain Services checkbox. This opens the Add features page. Select Add Features. Click Next.
Click Next On the "Select features" and "Active Directory Domain Services" page.
On the "Confirm installation selections" page, click Install. Depending on the speed of the computer, installation may take several minutes. When the installation completes, click Close.
On the Server manager menu, select the notification icon next to the flag in the top right corner. On the menu that opens when you select the notification icon, select Promote this server to a domain controller. This will start the Active Directory Domain Services Configuration Wizard.
On the Deployment Configuration page, select Add a domain controller to an existing domain and ensure that the domain name is set to tailwindtraders.internal.
You must re-authenticate the administrator account. Select Change. Enter Administrator & password for the user. Click OK. Click Next.
On the Domain Controller options page, accept the default settings and provide the Directory Services Restore Mode (DSRM) password. To do this, enter the password twice and Click Next.
Proceed by clicking Next on the DNS Options page. Continue by clicking Next on the Additional Options page. Advance by clicking Next on the Paths page. Finally, move forward by clicking Next on the Review Options page.
On the Prerequisites Check page, click Install. The installation will take several minutes depending on the speed of the virtual machine. The virtual machine will restart.
Transfer Flexible Single Master Operations Roles
In this procedure, you migrate the RID Master role from the domain controller TAILWIND-DC1 to TAILWIND-MBR1.
On TAILWIND-MBR1, under Tools open Active Directory Users and Computers.
In the navigation pane, right-click Active Directory Users and Computers, point to All Tasks, and then select Operations Masters.
On the RID tab, select Change, select Yes, and then click OK.
Click Close to close the Operations Masters dialog box.
Create an Active Directory site and configure a subnet for that sit
In this procedure, you establish an Active Directory site and configure a corresponding subnet to associate with it.
On TAILWIND-DC1, sign in with the username & password you configured for the default administrator account.
Open Active Directory Sites and Services from the Tools menu.
Right-click Sites, select New site, and type Sydney as the site name.
For the Link Name, select DEFAULTIPSITELINK and click OK twice.
Expand the Sites folder.
Right-click **Subnets and select New Subnet.
As the Prefix, type 172.16.1.0/24, select Sydney as site name and click OK.
Close Active Directory Sites and Services.
Managing domain controller functionalities involves monitoring health, optimizing performance, and ensuring high availability through Flexible Single Master Operations (FSMO) role management and replication. By following these steps, you maintain a resilient AD environment, critical for enterprise network operations.
