To create a server running on Server Core installation you need to have the following handy:
■ The Windows Server 2008 installation media
■ The product key
■ A computer with the recommended configuration for a Server Core installation
Before you begin, make sure you have clean or newly formatted hard disks or volume that you can allow installation to format for you. You cannot upgrade from a previous version of Windows Server to a Server Core installation. You also cannot upgrade from a full installation of Windows Server 2008 to a Server Core installation. Only a clean installation is supported.
Be sure of your needs and configuration before you start. Once you start a Server Core installation you cannot go back later and try upgrading it to a full installation of Windows Server 2008 with the Windows UI. Microsoft does not support that route and you would have to blow away the Server Core installation and start all over again.
To install a Server Core installation, perform the following:
1. Insert the Server Core Windows Server 2008 installation media into the DVD drive.
2. The auto-run dialog box will now appear. Click the Install Now option.
3. The installation wizard takes you through the instructions to complete Setup.
4. After the installation, press Ctrl+Alt+Delete and click Other User. At the login enter Administrator with a blank password, and then press Enter. You will now be able to log in and you will have the chance to set a password for the Administrator account.
