Note that, during the install, Windows may generate an error claiming that it could not find a file needed for DHCP installation. The wizard should automatically find the file and allow you to select it.
After that, the wizard should resume the installation process. DHCP has now been successfully installed and we are ready to configure it. We will create a new scope and configure some of the scope's options. To begin:. Keep that in mind because it will be significant later on. Right-click the server node in the left pane and choose New Scope. This will launch the New Scope Wizard. Specify a scope name and scope description.
The scope name can be anything, but we certainly want to name it something that describes the scope's purpose. The scope Description is not required. It is there in case we needed to provide a broader description of the scope. Specify an IP address range and subnet mask. For the Start IP address enter Finally, specify a subnet mask of Specifying the IP address range of a scope requires some knowledge of subnetting. Each scope in a DHCP server holds a pool of IP addresses to give out to clients, and the range of IP addresses must be within the allowed range of the subnet that you specify on the subnet mask field.
For simplicity we entered a classful, class C IP address range from Notice that the range encompasses the IP address of our server, the DNS servers and the default gateway, meaning that the DHCP server could potentially assign a client an IP address that is already in use! Do not worry -- we will take care of that later. Specify IP addresses to exclude from assignment. For the Start IP address , enter Certain network devices, such as servers, will need statically configured IP addresses.
The IP addresses may sometimes be within the range of IP addresses defined for a scope. We have the opportunity here to define those IP addresses that are to be excluded. We specified IP addresses Choosing No will allow you to configure these options at a later stage. The router, or gateway, IP address may be entered in next. The client computers will then know which router to use.
In the following window, the DNS and domain name settings can be entered. You can just input the server name into the appropriate box and press "Resolve" to allow it to find the IP address itself. The last step is to activate the scope - just press next when you see the window below. The DHCP server will not work unless you do this. The DHCP server has now been installed with the basic settings in place. The next stage is to configure it to the needs of your network structure.
The address pool displays a list of IP ranges assigned for distribution and IP address exclusions. You are able to add an exclusion by right clicking the address pool text on the left hand side of the mmc window and selecting "new exclusion range".
This will bring up a window as seen below which will allow you to enter an address range to be added. Entering only the start IP will add a single IP address. This means that the specific network client will have the same IP for as long as you wanted it to. To do this you will have to know the physical address MAC of each network card.
The new reservation will be added to the list. As an example, I have reserved an IP address These logs may explain why you cannot start the DHCP service. Skip to main content.
