Windows Server 2003, Standard Edition: System requirements
To ensure adequate performance, make sure that computers on which you install or upgrade to Windows Server 2003, Standard Edition meet the following requirements:
For an x86-based computer:
One or more processors with a recommended minimum speed of 550 megahertz (MHz). The minimum supported speed is 133 MHz. A maximum of four processors per computer is supported. Processors from the Intel Pentium/Celeron family, AMD K6/Athlon/Duron family, or compatible processors are recommended.
256 megabytes (MB) of RAM (recommended minimum). 128 MB is the minimum supported, and 4 gigabytes (GB) is the maximum supported.
For computers with more than 4 GB of RAM, be sure to confirm hardware compatibility by clicking the appropriate link in Support resources.
For an x64-based computer:
One or more processors with a minimum speed of 1.4 gigahertz (GHz). A maximum of four processors per computer is supported.
512 MB of RAM (minimum).
For computers with more than 4 GB of RAM, be sure to confirm hardware compatibility by clicking the appropriate link in Support resources.
A hard disk partition or volume with enough free space to accommodate the setup process. To ensure that you have flexibility in your later use of the operating system, we recommend that you allow considerably more space than the minimum required for running Setup, which is approximately 1.25 GB to 2 GB for x86-based versions of Windows Server 2003, and 4 GB for x64-based versions of Windows Server 2003. The larger amount of space is required if you are running Setup across a network instead of from a CD-ROM, or if you are installing on a FAT or FAT32 partition (NTFS is the recommended file system).
In addition, a domain controller upgrade from Windows NT 4.0 could require much more space than other upgrades or installations, because the existing user accounts database can expand by as much as a factor of ten during the upgrade, as Active Directory functionality is added.
Note
The setup process requires the free disk space described in the previous paragraphs. After Setup is finished, actual hard disk space used for the operating system will be more than the free space required for Setup, because of space needed for the paging file, for any optional components you install, and (on domain controllers) for user accounts and other Active Directory information. The usual size for the paging file is 1.5 times the size of the RAM. For more information, see the following:
Change virtual memory settings
Specify what happens when the system stops unexpectedly

Understanding Active Directory
For additional information about planning the sizes of disk partitions or volumes, including information about creating a separate partition for Remote Installation Services, see Considerations when planning disk partitions and Remote Installation Services system requirements.
A VGA or higher-resolution monitor (Super VGA 800x600 or higher is recommended), keyboard, and (optionally) a mouse or other pointing device.
As an alternative, for operation without a monitor or keyboard, you can choose a remote diagnostic and support processor that is designed for products in the Windows Server 2003 family. For more information about hardware compatibility, click the appropriate link in Support resources.
For CD-ROM installation:
- A CD-ROM or DVD drive.
For network installation:
One or more network adapters and related cables that are designed for products in the Windows Server 2003 family. For more information about hardware compatibility, click the appropriate link in Support resources.
A server from which to offer network access for the Setup files.
For additional hardware-based functionality:
- Appropriate hardware for the functionality you require. For example, if you require sound, you must have a compatible sound card with speakers or headphones. If you plan to support network clients, the servers and clients must have appropriate network adapters and cables.
