DNS Domain name server

DNS mainly provides the host name resolution function, which in the network as the domain name and the IP address mapping of a distributed database, can make users more simple and convenient access to the Internet site, but not to remember although the machine can be directly recognized but it is very inconvenient to human memory IP address. In simple terms, the role of DNS is--the mapping of IP address <-> host name (domain name). and in Win08r2, DNS is the basis for the normal operation of the ad environment.

DNS domain name resolution (hostname resolution): By accessing hostname, the process of obtaining hostname corresponding IP address is called Domain name resolution.

FQDN: (Fully qualified domain name) fully qualified domain name, refers to the hostname plus the full path, all the domain members in the sequence are listed in the full path. The domain name can be logically and accurately represent where the host is, or it can be said that the full domain name is a complete representation of the host name. From the information contained in the full domain name, you can see the location of the host in the domain tree. fqdn= host name. DNS suffix

There are two ways to hostname to IP address mappings:
1) Static mapping (Hosts file), there is a Hosts file (C:\Windows\System32\drivers\etc\hosts) on each computer. Configure the host name to the IP address mapping, the different computers independently maintain their own mapping tables, and only for the use of this device;

2) Dynamic mapping, the deployment of Domain name resolution system (DNS), the DNS server configured hostname to IP address mapping, when you need to access the target host through hostname, you need to the DNS server to query the IP address of hostname.

Note: in resolving the domain name, the first method of static domain name resolution, if the static domain name resolution is not successful, then use dynamic Domain name resolution. Some commonly used domain names can be put into static domain name resolution table, which can effectively improve the efficiency of domain name resolution.

DNS Install Done

Principle of DNS Server

Query Method
1) Recursive query: The DNS client directly requires a full parse result, that is: The DNS client can only be successful or failed (such as home internet).
2) Iterative query: The DNS client can only get the address of the next DNS server. The DNS server returns the correct address if the DNS client requests data, and returns a pointer if the DNS server does not request data (referring to the next DNS server), and continues the query layer by pointer.

3) Forward query: Find IP address by domain name
4) Reverse query: Find domain name by IP address

Application of the DNS service ad Active Directory

Active Directory is a directory service for Windows Standard Server, Windows Enterprise Server, and Windows Datacenter server. In Short, AD provides a unified identity authentication solution for all services on WindowsServer.

Active Directory provides the following features primarily:
① Basic network services: including DNS, WINS, DHCP, Certificate Services, and so on.
② Server and client Computer Management: Manage server and client computer accounts, join domain management for all servers and client computers, and implement Group Policy .
③ User Service: Manage user domain account, user information, enterprise Address Book (integration with e-mail system), user group management, user identity authentication, user authorization management, etc., implement group management policy on demand.
④ Resource Management: Manage network resources such as printers and file sharing services.
⑤ Desktop Configuration: The system administrator can centrally configure various desktop configuration policies, such as: Limitations of interface features, application execution characteristics restrictions, network connection restrictions, security configuration restrictions, and so on.
⑥ Application System Support: supporting financial, personnel, e-mail, Enterprise information portal, office automation, patch management, anti-virus systems and other applications.
As can be seen from the features provided by ad above,Active directory service is the core component of the Windows platform, which provides a powerful means for users to manage the identities and relationships of each component of the network environment.
