Features Include:

• Everything in Windows Server 2003 Standard plus:
• Cluster service - Server clusters provide high availability and disaster tolerance for mission-critical database management, file sharing, intranet data sharing, messaging, and general business applications. With Windows Server 2003, Enterprise Edition, and Windows Server 2003, Datacenter Edition, cluster service supports up to eight-node clusters for increased flexibility in adding and removing hardware in a geographically dispersed cluster environment. The cluster service also provides improved scaling options for applications.
• 64-bit support - Windows Server 2003, Enterprise Edition, is available in both 32-bit and 64-bit versions. The 64-bit version is optimised for intensive memory or computational tasks, such as mechanical design, computer-aided design (CAD), professional graphics, high-end database systems, and scientific applications.
  
• Multiprocessor support - The Windows Server 2003 family scales from single-processor solutions all the way up to 32-way systems. Windows Server 2003, Enterprise Edition, supports servers with up to 8 processors, and Windows Server 2003, Datacenter Edition, supports up to 32 processors.
  
• Metadirectory Services support - Microsoft Metadirectory Services (MMS) helps organisations integrate identity information from multiple directories, databases, and files with Active Directory. MMS provides a unified view of identity information, enables the integration of business processes with MMS, and helps synchronise identity information across an organisation.
  
• Hot Add Memory - Hot Add Memory allows ranges of memory to be added to a computer and made available to the operating system and applications as part of the normal memory pool. No rebooting and no downtime are required. This feature currently operates only on servers that have hardware support for adding memory while the server is operating. For these servers, the act of installing memory automatically invokes the Hot Add Memory feature in Windows Server 2003, Enterprise Edition.
  
• Non-Uniform Memory Access (NUMA) - System firmware can create a table called the Static Resource Affinity Table that describes the NUMA topology of the system. Windows Server 2003, Enterprise Edition, uses this table to apply NUMA awareness to application processes, thread default affinity settings, thread scheduling, and memory management features. Additionally, the topology information is made available to applications using a set of NUMA application programming interfaces.
  
• Terminal Services session directory - This load balancing feature allows users to reconnect easily to a disconnected session on a server farm running Terminal Services. Session directory is compatible with the Windows Server 2003 load balancing service and is supported by third-party external load balancer products.
  
• Windows System Resource Manager - A feature in both Windows Server 2003, Enterprise Edition, and Windows Server 2003, Datacenter Edition, the Windows System Resource Manager (WSRM) enables an administrator to allocate CPU and memory utilisation on a per-application basis. This is a useful tool for server consolidation.
