Microsoft Windows Server 2003 is an operating system and was released in 2003 by Microsoft as a successor for the Windows 2000 Server products. The internal version number for Microsoft is NT 5.2. Compared to Windows 2000 Server, it contains no fundamental innovations, but many small new features in detail. Especially in the field of security, many improvements have been made, especially in some particularly criticized default settings. For example, specialized applications such as Internet Information Server are no longer installed by default, so that a better related to the task system can be built.

Windows Server 2003 on workstations

There are always users who want to use Windows Server 2003 as a desktop installation, provided that they have the opportunity. There are two groups of users:

The first group used Windows Server 2003 as it is. That is, it is quite normal installed as a server operating system and only the required functions are activated.

The second group, however, pursued a different approach: Normally when using a server operating system forced more expensive, server-specific versions of some programs (such as antivirus software) to use. This necessity is thereby circumvented through minor modifications in the registry, because the operating system then appears to the outside as a workstation version. In this case, the benefits of the regular version not lost. For example, Windows Update will continue to be conducted with the higher priority server. Another related effect is the change-over to the Windows logon used in Windows XP.

Advantages and disadvantages compared to Windows XP

Windows Server use on a workstation in 2003, has the following additional advantages over Windows XP 32 -bit:

  • Newer kernel, which is smaller and more responsive
  • When installed 4GB RAM better utilization of memory ( full 4 GB compared to max. 3.2 GB for XP)
  • Increased safety when using the Internet Explorer
  • Several minor improvements and new features (for example, the updated storage stack)
  • Increase the network performance through improved network stack and support for TCP Chimney and RSS
  • GPT support for large hard drives (Service Pack 1)

Windows Server 2003 is by adapting to the workstation but no actual Windows XP. The disadvantage is the lack of both the modern (restricted) user account management and system recovery. There is also software which requires, among server operating systems use special versions with paid licenses. For example, the use of some free virus scanners on Windows Server 2003 is not possible.

But it is possible to transmit the missing data from an existing XP installation.

The use of the 64- bit version of Windows Server 2003 as a replacement for Windows XP x64 does not make sense, because the 64 -bit edition of Windows XP is already based on Server 2003.

Windows Storage Server 2003

The Windows Storage Server 2003 (WSS2003) is a version for Network Attached Storage. This version has limited functionality, but is cheaper. Applications include SQL server, file server or mail and Exchange server. Since 2006 he has been available only in the R2 version. The server comes pre-installed on hardware, and can be managed via Web interface.
