In this section: • Point out that this basic design process is useful for designing a network infrastructure. At a high level, it is the process by which all networks are designed, implemented, and managed. • Emphasize that this model is generic in nature. Organizations typically customize the model to suit their unique situations and design methodologies. Avoid spending time discussing implementation and management philosophies. • Some students may have good methodology skills. Avoid spending too much time on the details of the methodology and avoid getting into a discussion about the relative merits of specific methodologies. • In the subsequent modules, students generate their own designs and strategies. Acknowledge that solutions may vary by student.  Microsoft Windows 2000 Networking Services Provide an overview of Windows 2000 networking services. In this section: • Emphasize that this course is based on services and options available in Microsoft Windows 2000 Advanced Server. • Explain that Microsoft Windows 2000 server products offer a number of distinct network technologies and services. These technologies address specific organizational needs and have both benefits and limitations. • Point out that designers must understand the organizational objectives to create a networking services design that best meets these objectives. • Avoid going into too much detail in this topic. The details come in the modules that follow. • This topic presents a good chance to find out how knowledgeable the students are in each of the technologies and to identify whether students require more background information on any given technology.  Translating organizational goals into a design Introduce the criteria used to evaluate and refine a design. In this section: • Point out the aspects for grouping design decisions and explain that these aspects are aimed at making a design process more consistent and logical. • Discuss each aspect and provide an example of how the aspect applies to a design. • Emphasize that the aspects are used in subsequent modules to analyze and design a networking solution. Module 1: Microsoft® Windows® 2000 Networking Services Infrastructure Overview v Module 1: Microsoft® Windows® 2000 Networking Services Infrastructure Overview 1 Overview  Introduction to Networking Services Design  Microsoft Windows 2000 Networking Services  Translating Organizational Goals into a Design To develop an effective networking services infrastructure, you must be able to analyze the organizational goals and translate them into specific design strategies. In your networking services design, you must take into account the existing infrastructure. You will base all of your design decisions on the existing infrastructure. In addition, your design must be easily managed so that the organization is able to maintain the infrastructure operation within design specifications. At the end of this module, you will be able to:  Describe the process for designing the networking services infrastructure.  Identify the Microsoft ® Windows ® 2000 networking services that make up a networking services infrastructure.  Describe the design aspects used to translate organizational goals into a networking services design. Slide Objective To provide an overview of the module topics and objectives. Lead-in When you design a networking services infrastructure, you must follow some general principles that apply to most networking scenarios. 2 Module 1: Microsoft® Windows® 2000 Networking Services Infrastructure Overview Introduction to Networking Services Design The cycle used for deploying networking services into a network consists of three main phases. You can further divide each phase of the deployment cycle into specific decisions. The characteristics of an organization make each network deployment cycle slightly different. Design A comprehensive design consists of several essential decisions. The selection of networking services is one of the decisions that requires knowledge of the existing infrastructure and current organizational goals. After you select the networking services to include in your design, you must consider how to combine the services. You need to combine the networking services to improve the administration and performance of the network. Finally, you must decide on a management strategy that ensures the design specifications are met on a day-to-day basis. Your management strategy must also specify actions taken, if any, when the network fails to meet the design specifications. Implement After your design is created and satisfactorily tested, the network design is ready for implementation. During this phase of the process, the network is configured to meet the specifications of the design. Management processes are put into place to collect information, and the network operation begins. Manage During this phase of the process, you begin collecting data on the day-to-day operation of the network. The data that you collect allows you to determine which actions are required to maintain the network within design specifications. If the network characteristics significantly differ from the design specifications, you may need to redesign the solution. Slide Objective To introduce the basic model of a networking services design cycle. Lead-in Although networking designs vary widely in their overall structure, you may notice that all networking designs have some common characteristics. Emphasize that the design phase of the process is the focus of this course. Do not spend time discussing the implementation or management components. Delivery Tip Ask the students to discuss their experiences and see how they fit into this model. Ask the students where pilot testing may fit into the deployment process. Some students may place pilot testing in design, others may place pilot testing in implementation. Module 1: Microsoft® Windows® 2000 Networking Services Infrastructure Overview 3    Microsoft Windows 2000 Networking Services  Designing the Network Foundation  Designing Internet Connectivity  Designing Remote Access Connectivity  Creating an Integrated Networking Services Infrastructure Design Microsoft Windows 2000 Advanced Server offers a number of networking services. These services were developed to address specific requirements within an organization. You can create a networking services solution to fulfill the connectivity needs of your organization. To design a solution, you must translate the goals of your organization into functional requirements and specifications. Each of the networking services implemented by Windows 2000 addresses a different set of requirements. Some are fundamental, such as Transmission Control Protocol/Internet Protocol (TCP/IP), which is required when you plan to implement the Windows 2000 Active Directory ™ directory service. Other networking services, such as Routing and Remote Access, address more specific needs like providing remote user connectivity. Slide Objective To introduce network services based on their function within a networking services infrastructure. Lead-in As part of your design, you can begin the selection of networking services based on the functionality they provide to an organization’s network. Delivery Tip Emphasize the fact that not all of these services apply to an organization. The services are designed to address a specific type of networking requirement. 4 Module 1: Microsoft® Windows® 2000 Networking Services Infrastructure Overview Designing the Network Foundation Name? IP Address TCP/IP Network  Base Protocol Support: TCP/IP  Networking Services: DHCP, DNS, WINS The foundation of your networking services design is based upon services that are common to all designs. These networking services provide support for an addressing structure, automated client configuration, and name resolution services. TCP/IP TCP/IP is an industry-standard, vendor-independent routable protocol. Many of the services provided in Windows 2000, such as WINS, DNS, Active Directory, or Internet Information Services (IIS), require TCP/IP. DHCP For TCP/IP networks, managing TCP/IP configurations manually can be a time-consuming task that is prone to errors. DHCP automates and manages the TCP/IP configuration of the computers on the network, including the IP address, subnet mask, default gateway, DNS server addresses, and WINS server addresses. DHCP reduces the administrative overhead associated with TCP/IP configuration. DNS DNS provides domain name resolution within the network. This allows computers within the network to use a fully qualified domain name (FQDN), such as www.microsoft.com. DNS resolves an FQDN to an IP address. FQDNs allow network designers to create meaningful resource names and implement DNS designs for resolving those names. DNS resolves FQDNs by querying a DNS database for a matching entry that relates FQDNs to IP addresses. Slide Objective To highlight the services that provide an IP networking infrastructure. Lead-in Basic networking requires services that provide critical functions such as data transmission, client configuration, and name resolution.
