The Resultant Set of Policy (RSoP) Wizard is provided to make policy implementation and troubleshooting easier. The RSoP Wizard is a query engine that works in two modes: logging mode and planning mode. In logging mode, the wizard polls existing policies and any applications associated with a particular user or computer, and then reports the results of the query. In planning mode, the wizard asks questions about a planned policy implementation, and then reports the results of the query.
As an administrator, you must be able to administer Group Policy to provide users with the access to resources they require. See Chapter 10, “Implementing Group Policy,” Chapter 11, “Administering Group Policy,” and Microsoft exam 70-291, “Deploying Software with Group Policy,” for details about Group Policy administration.
DNS is a service used in Transmission Control Protocol/Internet Protocol (TCP/IP) networks, such as the Internet, to locate computers and services through user-friendly names. DNS provides a method of naming computers and network services using a hierarchy of domains. When a user enters a user-friendly DNS name in an application, DNS services can resolve the name to other information associated with the name, such as an IP address. For example, it’s easy for most users who want to locate a computer on a network to remember and learn a friendly name such as example.microsoft.com. However, computers communicate over a network by using numeric addresses. DNS provides a way to map the user friendly name for a computer or service to its numeric address. If you have used a Web browser, you have used DNS.
Active Directory uses DNS as its domain naming and location service. DNS provides the following benefits:
DNS names are user friendly, which means they are easier to remember than IP addresses.
DNS names remain more constant than IP addresses. An IP address for a server can change, but the server name remains the same.
DNS allows users to connect to local servers using the same naming free practice tests convention as the Internet.
