DHCP Server "Lease duration" little Pass

Sales of the LAN scale is increasing, the number of clients increased sharply, sales department of the network management wax gourd to avoid manually assigning IP addresses to clients, want to use DHCP server to achieve dynamic allocation of IP addresses. In this way, the IP address of the client is often changed, and the day-to-day maintenance work is caused by difficulties.

How can the client get the IP address assigned by the DHCP server and have these dynamically assigned IP addresses for a long time? Wax gourd found the LAN World "celebrity" jelly, ask him to help solve this problem.

Smart jelly thought of it. The use of the DHCP server's "lease duration" parameters to set up, you can solve this problem. In the end is how to achieve it? Wax gourd or confused. Jelly on the Windows Server 2003 system DHCP server as an example, explained to him the specific implementation process.

Installing the DHCP service

Because the Windows Server 2003 (Windows 2003) system defaults to no DHCP service installed, Jelly first installs the DHCP service.

On the Windows 2003 server, click start → settings → control Panel, and then run Add or Remove Programs and switch to the Add/Remove Windows Components page in the pop-up window. Next, select the Network Services option in the Windows Components Wizard dialog box and click the "Details" button below.

After selecting the Dynamic Host Configuration Protocol (DHCP) option in the Pop-up Network Services dialog box (Figure 1), click the OK button. Then click the Next button in the Windows Components Wizard dialog box to begin configuring, installing, and finally clicking the "Finish" button.

Jelly hints the full name of DHCP is the Dynamic host Configuration Protocol, which has a built-in DHCP server that unifies IP configuration information for clients in the network, such as IP address, subnet mask, default gateway address , WINS server address and DNS server address, which eliminates the hassle of a network administrator manually configuring the client.

Creating scopes

Jelly After you install the DHCP service on a Windows 2003 server, to assign an IP address to a client within a network segment, you first have to create a new scope.

In the DHCP Manager window, right-click the DHCP server option and select the new scope option from the shortcut menu that pops up (Figure 2).
