Installing Windows Server 2008 R2

System Requirements & Setup

Written in January 17, 2026

Released in 2008, Windows Server 2008 was the successor to Windows Server 2003 and represented a major leap forward in server management. It introduced "Server Core," a minimal installation option without a graphical user interface, designed to reduce the attack surface and system overhead for specific server roles like DNS or DHCP.

Instructions

To run Windows Server 2008 smoothly in VirtualBox, your virtual machine should be configured with a minimum of 512 MB of RAM (though 2 GB is recommended for GUI installations), at least 1 CPU core (2 cores for better stability), and assigned 10 GB to 40 GB of storage space.
  1. Open your virtualization software and create a new VM.
  2. Assign resources (RAM, CPU, disk space) as needed.
  3. Mount the Windows Server 2008 installation ISO.
  4. Start the VM.
  5. Follow on-screen prompts to start setup.
  6. Accept default or recommended settings when partitions are shown.
  7. Create a strong administrator password. Must include uppercase, lowercase, number, and symbol (or just three of them) (Example: EndUser123&).
  8. Set the time zone to whatever time zone you are.
  9. Go to Control Panel → Network and Sharing Center → Local Area Connection → Properties.
  10. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties. (We're going to make our IP into a static one)
  11. What I used -> IP address: 192.168.1.2, Subnet mask: 255.255.255.0, Default gateway: 192.168.1.1.
  12. Click OK to apply changes.
  13. Rename the server to whatever name you want. Path: System Properties → Computer Name → Change.
  14. Open Server Manager.
  15. Click Add Roles.
  16. Select Active Directory Domain Services (AD DS) and proceed with installation.
  17. This installs Microsoft services like Group Policies.
  18. Run Active Directory Domain Services Installation Wizard.
  19. Choose to Create a new domain.
  20. Enter domain details: (What I used -> Domain Name: bsit.com, Domain Administrator Account: bsit\administrator).
  21. Select minimum server OS level: For me, Windows Server 2008.
  22. If a Delegation message appears, it is normal—it assigns control to the domain.
  23. Log in using bsit\administrator.
  24. Check Administrative Tools → Active Directory Users and Computers to ensure your server and domain are visible.
  25. Confirm your domain is ready for managing users, groups, and policies.
