Know how to install and configure DNS. DNS can be installed before, during, or after installing the Active Directory service. When you install the DNS server, the DNS snap-in is installed, too. Configuring a DNS server ranges from very easy to very difficult, depending on what youre trying to make it do. In the simplest configuration, for a caching-only server, you dont have to do anything except make sure the servers root hints are set correctly. You can also configure a root server, a normal forward lookup server, and a reverse lookup server.
Know how to create new forward and reverse lookup zones. You can use the New Zone Wizard to create a new forward or reverse lookup zone. The process is substantially the same for both types, but the specific steps and wizard pages differ somewhat. The wizard will walk you through the steps, such as specifying a name for the zone (in the case of forward lookup zones) or the network ID portion in the network that the zone covers (in the case of reverse lookup zones).
Know how to configure zones for dynamic updates. The DNS service allows dynamic updates to be enabled or disabled on a per-zone basis at each server. This is easily done in the DNS snap-in. Know how to delegate zones for DNS. DNS provides the ability to divide the namespace into 1 or more zones, which can then be stored, distributed, and replicated to other DNS servers. When delegating zones inside your namespace, be conscious that for each new zone you create, youll need delegation records in other zones that point for the authoritative DNS servers for the new zone.
Understand the tools that are offered for monitoring and troubleshooting DNS. You can use the DNS snap-in to do some basic server testing and monitoring. More important, you use the snap-in to monitor and set logging options. Windows Server 2008 automatically logs DNS events in the event log below a distinct DNS server heading. nslookup offers the ability to per- form query testing of DNS servers and to obtain detailed responses at the command prompt. You can use the command-line tool ipconfig to view your DNS client settings, to view and reset cached details used locally for resolving DNS name queries, and to register the resource records for a dynamic update client. Also you can configure the DNS server to create a log file that records queries, notification messages, dynamic updates, and various other DNS facts. Finally you can use dnslint. Microsoft Windows Server 2008 DNS can use the dnslint command-line utility to help diagnose some common DNS name resolution issues and to help diagnose prospective problems of incorrect delegation.
