How to Set up an intranet temporary DHCP Service (1)

For small and medium-sized enterprises, the DHCP service is probably one of the most common network services. Many enterprise network administrators use the DHCP component function in the windows server operating system to establish corresponding services, however, have you ever encountered the need to temporarily enable the DHCP service? It is inconvenient to install the windows server operating system and set the release region if you still follow the traditional DHCP service enabling method, so is there any way to help us simplify and simplify the establishment of an Intranet temporary DHCP service? So that the DHCP service can automatically assign IP addresses and other network parameters as needed? The answer is yes. Next we will learn how to easily switch the Intranet DHCP service through third-party gadgets.

I. When do I need to use the Intranet temporary DHCP service:

In my personal experience, the DHCP service is mainly used in the Intranet management process in the following two places. Of course, each enterprise may encounter similar problems, which should be solved by the enterprise itself according to the actual situation.

1) DHCP service is required for GHOST:

First, when we install and deploy a data center, we need to re-install the various operating systems of the data center. Because most computer rooms have the same hardware configuration, therefore, we can use GHOST to install the operating system of the IDC. The traditional method is to install the system through a GHOST on the CD, but now there is a new method, that is, to use the network to implement the network GHOST, we can publish the network GHOST server on a server, and then the common computers in the machine room can directly download the GHOST program from the server and restore the system through the network, the advantage of restoring the operating system through the network GHOST method is obvious. On the one hand, it saves us time to maintain the data center, and the network administrator does not need to install the operating system on one platform, the entire installation is carried out in batches and in a coordinated manner. On the other hand, this network GHOST restoration method also reduces the wear of the optical drive and the burning of the GHOST disc, saving maintenance costs for a certain program. However, the network GHOST cannot be used at will. Just as the computer uses the network normally, each GHOST client must have an IP address, how can I assign IP address information to each client without installing the system? In this case, a DHCP service is required to assign network parameters such as IP addresses to the GHOST in each network through the DHCP server in the data center. After the data center Maintenance and GHOST recovery are complete, we can disable the temporary DHCP service.

2) DHCP service is required for network device initialization:

In addition to the application features mentioned above, some network devices purchased by our company, such as network printers and NAS network storage devices, also need to use the DHCP service during initialization, although a network device usually has a default IP address or provides a management tool for us to conveniently set up, many times it is impossible to configure the parameters of the network device through these methods due to one reason or another, at this time, the temporary DHCP service is required to assign addresses for these network devices, and then locate the IP addresses of the network devices through the cache information of the DHCP address pool, and then perform relevant configuration. After the configuration is complete, disable the temporary DHCP.

We need to enable the temporary DHCP Application on the enterprise intranet because of all the above circumstances, and then disable the service after use, we can re-install the windows server to enable the DHCP function component to set the role area, but it is a bit difficult, complicate the simple problem. For this reason, we should learn how to simplify and build an intranet temporary DHCP service. Next we will ask the readers of IT168 to follow the author to learn the implementation method.
