How to Promote Windows Server 2012 R2 to Domain Controller
In the modern IT landscape, domain controllers play a crucial role in managing network resources and ensuring seamless user access. Windows Server 2012 R2, with its robust features and enhanced security, is a popular choice for organizations looking to establish a robust domain infrastructure. Promoting a Windows Server 2012 R2 to a domain controller is a straightforward process, provided you follow the right steps. This article will guide you through the entire process, ensuring a smooth transition from a standard server to a domain controller.
Understanding the Basics
Before diving into the promotion process, it is essential to understand the basics of a domain controller. A domain controller is a server that authenticates and authorizes users and computers in a Windows domain. It stores information about the domain, such as user credentials, group policies, and network resources. By promoting a Windows Server 2012 R2 to a domain controller, you are essentially turning it into a central authority for managing user accounts and resources within your network.

Before you begin the promotion process, ensure that your Windows Server 2012 R2 meets the following prerequisites:
1. Install Windows Server 2012 R2 with a GUI (Graphical User Interface).
2. Ensure that the server has a static IP address.
3. Install the .NET Framework 3.5 feature on the server.
4. Configure the server with a strong password for the built-in Administrator account.
