Please click HERE for the steps to configure DHCP Server on Windows Server 2012 Essentials.
By default Small Business Server 2011 Essentials does not install the DHCP Server role and DHCP duties are handled by your router. In some cases you may want to have the SBS 2011 Essentials server be the DHCP server instead of your router. To do so, first, you need to assign a static IP address to the server's network card. Installing the DHCP Server role without a static IP address is not recommended.
To find out your current TCP/IP settings, launch an elevated command prompt and run the command ipconfig, and make a note of the IPv4 address, Subnet Mask and Default Gateway.
Launch ncpa.cpl from the run menu or an elevated cmd prompt, which will load the Network Connections control panel. Right click on your network card and select Properties which will bring up the following screen as shown below.
Select Internet Protocol Version 4 (TCP/IPv4) and then click Properties
You will want to enter an IP address within the same network range as noted earlier (e.g 192.168.15.2). Additionally, add the exact same subnet mask and default gateway that was identified earlier when running ipconfig, and lastly enter the IP address of the server as the preferred DNS server and then click Ok and then Close.
To install the DHCP Server role on SBS 2011 Essentials follow these steps:
Once you have successfully installed and configured the DHCP Server role on SBS 2011 Essentials, you need to turn off DHCP on the router. To do this, follow the instruction manual that came with the router. Next, you need to renew the IP address on the clients. To do this, launch an elevated command prompt on the workstation and run ipconfig/release && ipconfig/renew.
Lastly, you may want to stop and disable the Windows Server LAN Configuration service on the client machines since its function is no longer required. To know more about this service, check out this great blog post from Sean Daniel: The Basics of Local DNS for Small Business Server 2011 Essentials
What's best practice? Using my DSL-Router to serve DHCP, or configuring SBS2011?
