Pre-installation for Windows 2000

Prior to the formal installation of Windows 2000, users need to understand the system requirements of Microsoft Windows 2000 to organize enough hard disk space and then plan for licensing, startup, and file systems. Additional add-ons help users to experience the features of Windows 2000 perfectly.

1.2.1 Understand system requirements

Windows 2000-installed computers or servers should use Pentium 200MHz or higher CPUs with at least 64MB in memory, and 128MB is recommended, which supports up to 8GB memory space. Given the complexity of the Windows 2000 operating system, the hard disk should have more than 2GB of space and be sure to have more than 850MB of space left over after the installation is complete.

When you install from a CD, you should choose a 1 2-speed or higher optical drive, which will ensure that you read the installer smoothly and quickly from the CD. When you install Windows 2000 over the network, additional space is required for 200MB, because there are additional driver files that need to be added to the network installation compared to the CD installation. In addition, you should use a Windows 2000-compatible network adapter and a corresponding cable to transfer data from the Web server where the installation files are stored.

To ensure that the installation is successful, you need to ensure that your computer hardware is fully compatible with Windows 2000 before you start the installer. A list of Windows 2000-compliant hardware is stored in the HCL.TXT file in the Windows 2000 Installer Support folder, and if the current computer's hardware is not in the list, you can consider replacing the computer's hardware. Otherwise, the impending installation is likely to suffer setbacks. When you need to know the latest hardware list, you can access the HTTP://WWW.MICROSOFT.COM/HWTEST/HCL URL directly.

1.2.2 Select installation mode

Upgrading the installation means that Windows 2000 is installed on an existing operating system. When you choose to reinstall, the computer's operating system is removed or installed on a hard disk or partition that does not have an operating system installed, requiring the user to back up the data that needs to be retained. If the version of Windows NT Server currently in use is less than 3.51, you cannot upgrade directly to Windows 2000, and you must upgrade to Windows NT 3.51 or Windows NT 4.0 before you can upgrade to Windows 2000.

In the process of upgrading the server, the system allows the user to choose where to store three important files, which are database files, log files, and system volume (SYSVOL) files. The database and log files can be placed on any type of partition (FAT, FAT 32, or NTFS), and the system volume files must be placed in an NTFS partition.

After you complete the upgrade of the primary domain controller, you can proceed to upgrade other backup domain controllers. The server that you upgraded first will be the template to replicate when you upgrade other domain controllers. When all the servers are completely upgraded to Windows 2000 domain controllers, you can change the domain from mixed mode (Windows NT domain controller can exist in this domain) to native mode (only Windows 2000 domain Builder can exist in that domain), and after you change to native mode, The system will not be able to return blending mode.
