About Windows Server 2008 Active Directory Domain Services (AD DS) Installation
When Windows Server 2008 R2 is installed, initially it works as a normal client operating system and does not provide any server specific services to other computers in the network. Moreover, right after the installation, Windows Server 2008 R2 can be added to the network only as a workgroup client with no additional features installed. In such cases, administrators cannot have centrally managed network, thus they must manage each computer in the network individually. Therefore, in order to centrally manage the LAN setup, they must install AD DS on Windows Server 2008 R2 which then promotes the network operating system to the domain controller.
Preparation for Active Directory Domain Services Installation
Before installing Active Directory Domain Services on Windows Server 2008 R2, the operating system must be prepared accordingly. Preparation of Windows Server 2008 R2 includes:
- Assigning a static IP address to the computer.
- Renaming the computer to something more specific and self-explanatory name.
- Verifying that the computer has correct time zone configured in it.
- Specifying appropriate IP address of any existing DNS server in the network.
Note: Loopback address (127.0.0.1) can be used in case no DNS server is present in the network, and administrators plan to install the DNS server role on the domain controller itself during AD DS installation.
- Checking if the computer is connected to the network and the entire network is running properly.
- Verifying that the computer has latest security patches and updates installed in it.
- Verifying if the computer has sufficient amount of free disk space to hold appropriate services and features along with all the required applications.
- Verifying that the physical security of the computer is strong and impeccable.
