I would like to share interactively on how to add Active Directory Domain Service (AD DS) Role in Windows Server 8 beta.
step1: Open Server Manager
step 2: On Add Roles and Features Wizard, click Next
step 3: On Select Installation type, choose Role-based or feature-based installation. Then click Next.
step 4: On Select destination server, select “select a server from the server pool“. Click Next.
step 5: On Select Server roles, tick “Active Directory Domain Services” to enable Active Directory.
step 6: Once you have checked the button, there are some features are required to be installed which are Remote Server Administration Tools, PowerShell, AD DS and AD LDS Tools. click “Add Features”. then click Next.
Step 7: On Select Features, click Next
step 8: On Active Directory Domain Services, click Next.
step 9: On Confirm Installation selections. it is ready to be installed, once ready, click Install.
On Result, it show the installation progress and just click Close. However, the AD roles are installed but have not yet deploy the domain controller. You have to promote a domain controller either using dcpromo or click “promote this server to a domain controller” on figure below.
