Microsoft Certified Systems Administrator (MCSA)

The Microsoft Certified Systems Administrator (MCSA) certification helps validate your ability to manage and troubleshoot network environments based on the Windows Server 2003 operating system.

It reflects a unique set of skills required to succeed in a variety of job roles, such as systems administrator, network administrator, information systems administrator, network operations analyst, network technician, and technical support specialist.

If you want to be certified on newer Microsoft technologies, such as Exchange Server 2010, Windows Server 2008, or SQL Server 2008, you should pursue the Microsoft Certified IT Professional (MCITP) certification.

And, if you have the MCSE on Windows Server 2003 certification, you can upgrade to the Microsoft Certified Technology Specialist (MCTS) and Microsoft Certified IT Professional (MCITP) on Windows Server 2008 certifications.
