This course is part two of a three-part series that provides the skills and knowledge necessary to implement a core Windows Server infrastructure in an existing enterprise environment. ISTA 230, Network and Services Fundamental is the prerequisite, and ISTA 332, Designing and Implementing Server Infrastructures, is the next course in this series. The three courses collectively cover implementing, managing, maintaining, and provisioning services and infrastructure in a Windows Server environment. While there is some cross-over in skills, concepts and tasks across these courses, ISTA 330 focuses more closely on administration, maintenance and troubleshooting tasks via an examination of advanced implementation and maintenance of core services, including Active Directory Domain Services (AD DS), group policies and file services and remote access. The goal of the course is to provide the student with both the practical hands-on skills necessary to implement, manage and maintain server infrastructures, but also to understand the theory and best practice that relate to successful Windows Server implementations. Class projects guide students in achieving these goals. In addition, by preparing the student to succeed with the related Microsoft Certification exams, this course is an essential step on the way to earning relevant Microsoft professional certifications.
