How DNS Works: Domain Name System(DNS)The logical structure of Windows Server 2. DNS involves DNS namespace partitioning, which extends the DNS domain name hierarchy into multiple subdomains. The physical structure of DNS involves distributing the DNS database using DNS servers to host DNS zones for the subdomains of the DNS domain name hierarchy. Both the DNS Client and Server service applications manage the physical DNS data in the DNS database. The Windows Server 2. Microsoft Windows XP and Windows 2. DNS Client service. This service performs all necessary DNS lookups and provides a local cache for DNS queries that reduces DNS network traffic and speeds name resolution. This service can be stopped and started using the Services console. Computers running Windows 2. Windows XP and Windows Server 2. DNS Client service by default. The Windows Server 2. DNS Client service performs the following tasks. Registers its names in DNS. Name resolution. Caching responses to name resolution queries. Removes previously resolved names from the cache when it receives a negative response for the name. Negative caching. Keeps track of transitory (Plug and Play) network connections and the DNS server lists based on their IP configurations. Maintains connection- specific domain name suffixes. Prioritizes which DNS servers it uses according to whether they respond to a query if multiple DNS server are configured on the client. Prioritizes the multiple A resource records it receives from a DNS server based on their IP address. Initiates a network failure timeout when all DNS Client service queries time out, and does not submit any queries for 3. This feature applies to every adapter separately. Windows XP, Windows 2. Windows Server 2. DNS client configuration involves the following settings in the TCP/IP properties for each computer: Domain Names. Domain names are to form the fully qualified domain name (FQDN) for DNS clients. Host names. A DNS computer or host name for each computer. For example, in the fully qualified domain name (FQDN) wkstn. DNS computer name is the leftmost label client. Primary DNS suffixes. A primary DNS suffix for the computer, which is placed after the computer or host name to form the FQDN. Using the previous example, the primary DNS suffix would be example. Connection- specific names. Each network connections of a multihomed computer can be configured with a connection- specific DNS domain name. Net. BIOS names. Net. BIOS names are used to support legacy Microsoft networking technology. DNS servers list. A list of DNS servers for clients to use when resolving DNS names, such as a preferred DNS server, and any alternate DNS servers to use if the preferred server is not available. DNS suffix search list. The DNS suffix search list or search method to be used by the client when it performs DNS query searches for short, unqualified domain names. Domain Names. The domain name is used with the client computer name to form the fully qualified domain name (FQDN), known also as the full computer name. In general, the DNS domain name is the remainder of the FQDN that is not used as the unique host name for the computer. For example, the DNS domain name used for a client computer could be the following: If the FQDN, or Full computer name, is wkstn. DNS domain names have two variations — a DNS name and a Net. BIOS name. The full computer name (a fully qualified DNS name) is used during querying and location of named resources on your network. For earlier version clients, the Net. BIOS name is used to locate various types of Net. BIOS services that are shared on your network. An example that shows the need for both Net. BIOS and DNS names is the Net Logon service. In Windows Server 2. DNS, the Net Logon service on a domain controller registers its service (SRV) resource records on a DNS server. For Windows NT Server 4. Domain. Name entry in Windows Internet Name Service (WINS) to perform the same registration and to advertise their availability for providing authentication service to the network. When a client computer is started on the network, it uses the DNS resolver to query a DNS server for SRV records for its configured domain name. This query is used to locate domain controllers and provide logon authentication for accessing network resources. A client or a domain controller on the network optionally uses the Net. BIOS resolver service to query WINS servers, attempting to locate Domain. Name [1. C] entries to complete the logon process. Your DNS domain names should follow the same standards and recommended practices that apply to DNS computer naming described in the previous section. In general, acceptable naming conventions for domain names include the use of letters A through Z, numerals 0 through 9, and the hyphen (- ). The use of the period (.) in a domain name is always used to separate the discrete parts of a domain name, commonly known as labels. Each label corresponds to an additional level defined in the DNS namespace tree. For most computers, the primary DNS suffix configured for the computer can be the same as its Active Directory domain name, although the two values can be different. Host Names. Computers using the underlying TCP/IP protocol of a Windows- based network use an IP address, a 3. IPv. 4) or a 1. 28- bit numeric value (in the case of IPv. However, network users prefer to use memorable, alphanumeric names. To support this need, network resources in a Windows- based network are identified by both alphanumeric names and IP addresses. DNS and WINS are two name resolution mechanisms that enable the use of alphanumeric names, and convert these names into their respective IP addresses. Net. BIOS vs. DNS Computer Names. In networks running Windows NT 4. Net. BIOS (Network Basic Input Output System) name. In Windows 2. 00. Windows XP, and Windows Server 2. DNS. In this implementation of DNS, a computer is identified by its full computer name, which is a DNS fully qualified domain name (FQDN). Primary DNS Suffixes. The full computer name is a concatenation of the single- label host name, such as hostcomputer, and a multilabel primary DNS suffix name, such as corp. DNS name of the Active Directory domain to which the computer is joined. Using the host and primary DNS suffix examples, the full computer name is hostcomputer. The host name is the same as the computer name specified during the installation of Windows Server 2. System Properties. The primary DNS suffix name is the same as the domain name specified during installation of Windows Server 2. System Properties. The full computer name is also listed in System Properties. In addition, connection- specific DNS suffixes can be applied to the separate network adapter connections used by a multihomed computer. Connection- specific DNS suffixes identify the host when it is connected to separate networks that use different domain names. When using connection- specific DNS suffixes, a full computer name is also a concatenation of the host name and a connection- specific DNS suffix. Using its host name and DNS suffixes, a single computer can have its full computer name configured using two possible methods. A primary full computer name, which applies as the default full computer name for the computer and all of its configured network connections. A connection- specific full computer name, which can be configured as an alternate DNS domain name that applies only for a single network adapter installed and configured on the computer. Note that when using Active Directory, by default, the primary DNS suffix portion of a computer’s full computer name must be the same as the name of the Active Directory domain where the computer is located. To allow different primary DNS suffixes, a domain administrator may create a restricted list of allowed suffixes by creating the ms. DS- Allowed. DNSSuffixes attribute in the domain object container.
