  • The 12 Essential Tasks of Active Directory Domain Services
    WHITE PAPER ACTIVE DIRECTORY DOMAIN SERVICES The 12 Essential Tasks of Active Directory Domain Services Using the right tools and processes helps reduce administrative overhead and ensures directory service is always available By Nelson Ruest and Danielle Ruest Sponsored by WHITE PAPER ACTIVE DIRECTORY DOMAIN SERVICES ABSTRACT Active Directory Domain Services (AD DS) administration and management includes Sponsored by 12 major tasks. These tasks cover a wide breadth of business needs and are not all performed solely by AD DS administrators. In fact, administrators can and should delegate several tasks to other members of their technical community, technicians, help desk personnel, even users such as team managers and administrative assistants. While delegation is a way to reduce the amount of work administrators have to do when managing AD DS infrastructures, it really only addresses one or two of the 12 tasks, for example, user and group administration as well as end point device administration. The other ten tasks can be staggering in nature—security, networked service administration, OU-Specific Management, Group Policy Object management and many more—and because of this can take up inordinate amounts of time. You can rely on Microsoft’s built-in tools to reduce some of this workload, but are the native tools enough? Perhaps it’s time to reduce AD DS administration overhead by automating most tasks and tightening internal security. Address this by first, determining what the twelve essential labors of Active Directory are and then, see how you can reduce AD DS workloads through the implementation of proper management and administration tools.

  • Microsoft Active Platform: a Development Platform for Internet-Based Distributed Computing
    Microsoft Active Platform: A Development Platform for Internet-Based Distributed Computing Backgrounder March 19977 Intent on increasing online efficiency while reducing development and training costs, businesses are demanding a single solution for storing, publishing and retrieving information, as well as for running line-of-business applications on internal networks and the Internet. The Microsoft® Active Platform meets this demand by providing a foundation for distributed computing. An integrated, comprehensive set of client and server development technologies, the Active Platform makes it easy for developers to integrate the connectivity of the Internet with the power of the personal computer. The Active Platform is based on the leading standards-based implementation of HTML from Microsoft, open scripting and component architecture. It allows developers to use the same tools and components they know and use today to build powerful applications easily for the Internet and intranets. This comprehensive set of tools and technologies provides a new application development approach across clients and servers using a single component model. By making optimal use of today’s tools and tomorrow’s Internet technologies, the Active Platform enables developers to make the transition into the new paradigm for desktop computing and capitalize on the new opportunities it presents. The Active Platform offers users and administrators a graphically rich, intuitive, easy-to-manage and consistent experience across platforms. Developers benefit from rich services built into the system and a uniform programming model across the client and the server that can be accessed from a consistent, integrated set of tools. Figure1. The Microsoft Active Platform brings information to the desktop from the Internet and intranets under the comprehensive interface of the Active Desktop.
