As would be expected, the Windows 2003 Server tools are intended for large networked systems and many are not appropriate for typical home systems. Nonetheless, many can be useful in a simple system. I have made a somewhat arbitrary selection of those that seem most helpful and discuss them below. Note that some of these tools are actually graphical (GUI) tools that are opened from the command line and this is indicated where it applies. A full list of the tools is available at the Microsoft download site. Once they are installed. the Help and Support Center will contain a list with descriptions and syntax for their use.
Many of the command-line tools from the Windows Server 2003 resource kit can be used in Windows XP. Some are described here.
