Windows Server 2008

A domain DNS server provides for the local mapping of fully qualified domain names to IP addresses. Because the DNS is a distributed database, the local DNS servers can provide record information to remote DNS servers to help resolve remote requests related to fully qualified domain names on your network.

You would create both a forward lookup zone and a reverse lookup zone on your Windows Server 2008 DNS server.

The DNS snap-in enables you to add or remove zones and to view the records in your DNS zones. You can also use the snap-in to create records such as a DNS resource record.

A caching-only DNS server supplies information related to queries based on the data it contains in its DNS cache. Caching-only servers are often used as DNS forwarders. Because they are not configured with any zones, they do not generate network traffic related to zone transfers.

The IP addresses supplied by the DHCP server are held in a scope. A scope that contains more than one subnet of IP addresses is called a superscope. IP addresses in a scope that you do not want to lease can be included in an exclusion range.

You can create a reservation for the device (or create reservations for a number of devices). To create a reservation, you need to know the MAC hardware address of the device. You can use the ipconfig or nbstat command-line utilities to determine the MAC address for a network device such as a computer or printer.

The DHCP server can supply a DHCP client an IP address and subnet mask. It also can optionally include the default gateway address, the DNS server address, and the WINS server address to the client.

The DHCP server must be authorized in the Active Directory before it can function in the domain.
