Windows Server 2003 is the direct successor of Windows 2000 Server. Compared to the 2000 version, many network features have been introduced or improved. The most important ones include, among others, IIS version 6.0, fixes in Active Directory service, as well as adding the Background Copy function. The system can still work with FAT, FAT32 and NTFS file systems. It is equipped with .NET Framework version 1.1. The system is equipped with a special edition of Internet Explorer. The program is also configured in such a way that it is practically impossible to run or download files or extensions that may harm the system.
New features of Windows Server 2003:
Most versions of Windows Server include support for terminal services (using the remote desktop protocol), allowing multiple simultaneous remote logins. This feature was first introduced in the special "Terminal Server Edition" of Windows NT Server 4.0, but became more important when it became a standard part of Windows 2000.
Internet Information Services (IIS) version 6.0 - again, IIS versions were available in Windows 2000 and earlier, but IIS was significantly improved in Windows Server 2003.
Active Directory - similarly to terminal services, significantly improved since Windows 2000.
Enhanced default security compared to previous versions, due to the built-in firewall and most services are disabled by default.
Message Queuing - significantly improved since Windows 2000
Manage Server - a role management tool that allows the administrator to select the functions that the server should provide.
Active Directory service improvements (such as the ability to deactivate classes from the schema or run multiple instances of a directory server (ADAM))
Improvements in the handling and management of group policies
Improved disk management, including backup capabilities.
Enhanced scripting and command line tools that are part of Microsoft's initiative to introduce a complete command shell into the next version of Windows.
Support for a hardware "watchdog" that can reboot the server if the operating system does not respond within a specified time.
Windows Server 2003 has been released in several editions: Small Business Server, Web Edition, Standard Edition, Enterprise Edition, Datacenter Edition, Compute Cluster Edition, Storage Server, External Connector
