In a network using TCP / IP protocol, each computer must have at least one IP address to communicate with other computer. In order to facilitate the unified planning and management of IP addresses in the network, DHCP (Dynamic Host Configure Protocol, Dynamic Host Configuration Protocol) is gone. Such network services facilitate effective management of client IP addresses in the campus network without having a manual designation IP address. DHCP service installation DHCP refers to the server to control a segment of IP address, and the client can automatically obtain the IP address and subnet mask assigned by the server when logging in to the server. First, the DHCP server must be a computer installed with a Windows 2000 Server / Advanced Server system; secondly, the computer that serves as a DHCP server needs to install the TCP / IP protocol, and set a static IP address, subnet mask, default gateway, etc. content. By default, DHCP is not automatically installed by the system as Windows 2000 Server, you must add it to: 1. Click "Start → Settings → Control Panel → Add / Remove Programs → Add / Remove Windows Components ", Open the corresponding dialog. 2. Use the left mouse button to click "Network Service" in the "Component" list box in the Selected Dialog box, click the [Details] button, and the dialog box with specific content appears. 3. Check "Dynamic Host Configuration Protocol (DHCP)" in the Subcombinate list box of Network Services, click the [OK] button, put it in Windows 2000 installation CD according to the screen prompt, copy the required program. 4. After restarting the computer, "DHCP" will appear under the "Start → Manage Tool", indicating that the DHCP service is successful. DHCP server authorization . The process of authorizing the DHCP server authorization is as follows: 1. Click "Start → Programs → Administrative Tools → DHCP" to open the DHCP console window. 2. In the console window, click the left mouse button to select the server name, then right-click, select "Authorization" in the shortcut menu, which takes a few minutes of waiting time. Note: If the system has no response for a long time, you can press the "Refresh" on the "Operation" in the F5 key or in the Select Menu tool, or turn off the DHCP console first, right-click on the server name. If the "Authorization" in the shortcut menu has changed to "Undo Authorization", it means that the DHCP server is authorized to succeed. At this time, the most obvious tag is the arrow in front of the server name to become a green downward arrow. In this way, this authorized DHCP server has the right to assign IP. Adding an IP address range When the DHCP server is authorized, it needs to set the IP address range. By setting the IP address range for the DHCP server, when the DHCP client applies for an IP address to the DHCP server, the DHCP server selects a dynamic allocation from the IP address that has not been used in the set IP address. The operation of adding an IP address is as follows: 1. Click "Start → Programs → Administrative Tools → DHCP" to open the DHCP console window.
