Practice: configure the DNS Client Domain Name Search suffix to construct a domain name for domain name resolution

2.1 practice: configure the client to use the DNS server to resolve the computer name

Purpose:

Ü in the Intranet, users are used to accessing resources using the computer name instead of the full name of the computer. You need to configure the client to create a domain name after the computer name is resolved, then, the IP address of the computer is resolved through the DNS server.

Enterprise environment:

There is an internal network in the Microsoft Hebei enterprise escort center network, which is connected to the Internet through ADSL. There is a domain environment in the intranet. Win2k3 is a computer in a working group. When a computer user accesses an intranet server, the server name is used instead of the full name of the server. The network administrator wants to configure the client to resolve the server name through the DNS server.

Lab environment:

Ü DCServer is the domain controller and DNS server in the ESS. COM domain. Install Windows Server 2008 Enterprise Edition,

Ü DHCPServer is a DHCP Server in the ESS. COM domain. It is installed in the Windows Server 2008 Enterprise Edition operating system and is responsible for allocating IP addresses to intranet computers.

Ü Research Server is a member Server in the ESS. COM domain. It is installed on the Windows Server 2008 Enterprise Edition operating system, and the IP address and DNS are set to automatically obtained.

Ü the Sales computer is a member of the ESS. COM domain. It installs the Vista enterprise operating system, and sets the IP address and DNS address to automatically obtain.

Ü Win2k3 is a computer installed in the working group on Windows Server 2003 Enterprise Edition.

2.1.1 configure the DHCP scope option DNS domain name

On DHCServer, click "start"> "program"> "management tool"> "DHCP" to open the DHCP management tool.

Right-click "scope options" and click "configuration options ".

In the displayed scope option dialog box, select "015DNS domain name", enter ess.com, and click "OK ".

2.1.2 test computer name resolution on the client

Perform name resolution tests on win2k3 in the Working Group. Set the IP address to be automatically obtained. Enter ipconfig/renew at the command prompt to refresh the IP address lease. Enter ipconfig/all to view the DNS suffix search list configured by the DHCP server.

Ping the computer name of the Research server. Note that the resolved result is the IP address corresponding to the research.ess.com domain name. The resolution result is returned by the DNS server.

For computers that use a fixed IP address, manually specify the DNS suffix to search for the list ., Open the TCP/IP properties dialog box for the local connection, set the IP address and DNS server to static, and click "advanced ".

Under the DNS tab of the Advanced TCP/IP Settings dialog box, select "Add the following DNS suffix" and click "add ". In the displayed dialog box, enter ess.com and click "add ". Of course, you can have multiple DNS suffixes. The client will add these DNS suffixes to construct domain names and find the IP addresses resolved by the DNS server.

At the command prompt, enter ipconfig/all to view the DNS suffix search list, which has added ess.com. ping dcserver to view the IP address resolved to dcserver.ess.com.
