Please read the manual of your router for this procedure and make sure not only IP4 DHCP server is disabled but also disable the IP6 DHCP server if you have one. Open Server Manager on your server and click on the Ethernet adapter that is used for your network. BTW, if you have more then one network adapter and you do not use them with your server I suggest you disable them in device manager or in the bios of your server. We need to find out what the IP address and gateway is when the server is still connected to the router with DHCP enabled. Click on status. Click details Write down the IPv4 Address and the Gateway. That is what we need later to set the server to use a static address. After you have done this close this window. Go back to the Nic properties and click Properties. Select TCP/IPv4 and click Properties. We found previously that the IP address handed out by our router was 192.168.160.128 and you could use that as the static address for your server but I always put the server on an address that ends on .5. That comes from the old days with SBS where this was done by the setup wizards. You can do the same as long as the address is on the same subnet as the default gateway. Click OK and close all windows. You can now disable the DHCP server on your router. From the Server Manager choose ‘Add roles and features’. Click Next Click Next Click Next Check DHCP Server Choose Add Features Click Next Click Next Click next. Choose Install. Setup installs the DHCP server and the options you choose. After it is ready click ‘Complete DHCP configuration’. Click Next Accept the defaults and click Commit Click Close after all is done. Configure the DHCP scope and options. From the Server Manager choose Tools –> DHCP Right Click the IPv4 hive and choose ‘New Scope’. Click Next. Give it a name and a description and click Next. I always choose to start at .20 and end at .254 but your ideas may differ. In this setup I create an exclusion from .20 to .25. Those IP addresses will be later used for printers. Click Next Yes, we want to configure options now. Click Next. Add the gateway and click next Our server is already completely installed and that means it is a domain controller and because it is the only domain controller in our domain it also has the DNS role installed and the setup wizard already found that we have a DNS server running at the IP address of our server. Click next. No WINS for our domain, click Next. Yes, activate the new scope and click next. Click Finish. Make sure you have all green checkmarks. If you do not have that restart the DHCP server and check again. Now it is time to start a client on your network and check if the DHCP server does the job for you! If you have verified all is working you can disable the service called ‘Windows Server LAN Configuration’. That service is only needed when the Essentials Server does not have the DHCP server role installed.
