DHCP Server Windows 2012R2 with out AD

Is it possible to install DHCP server role with out installing Active directory.  

Working on the decommission of an SBS2008.  I was just in a meeting today when informed the company was going to Mac for their workstation.  The SBS was already in process of decommission, Exchange has been moved out to the cloud office 365.

They will still need a handful of windows machines to work with one line of business products. They are checking to see if those machines need to be joined to AD.  

If they are going Mac, I really don't see the need for AD because AD does not interface with Mac as far as I know.  However, they will need DHCP,  DNS, and file server to for the Mac to connect to.  The Macs would be connecting to Windows 2012R2 in a work group peer to peer and users names passwords would have to be done on a peer to peer basis.  Macs currently authenticate that way anyway.  User name and password have to be input anyway to connect to a share on the network.

dns,dhcp needs AD
You can add mac to domain
And so mac machines can access network resources i would recommend keep AD and use domain users its supported
I second king2002. I would leave AD and install all other services with AD. Much tighter control of network and shares thru AD than stand alone. We manage a few hybrid MAC-PC networks and saves a lot of time to have AD
DHCP does not rely on AD in any way (but with tie-ins to DNS, it can be advantageous to have your DHCP as a member of the domain).
However, current Mac OS (I've done it with Leopard through El Capitan) have no problem joining to AD.  Having a central login store is very handy in my opinion.  If everyone used a domain login (everyone has their own individual login), then access to network resources (e.g. file shares) becomes much easier to manage.

It's certainly possible to do all of this in a peer-to-peer fashion, but I don't see the benefit in doing so.

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

For a DHCP server that is not a member of the Active Directory domain, the DHCP Server service sends a broadcast DHCPInform message to request information about the root Active Directory domain in which other DHCP servers are installed and configured. Other DHCP servers on the network respond with a DHCPAck message, which contains information that the querying DHCP server uses to locate the Active Directory root domain. The starting DHCP server then queries Active Directory for a list of authorized DHCP servers and starts the DHCP Server service only if its own address is in the list.

Although it is not recommended, you can use a stand-alone server as a DHCP server as long as it is not on a subnet with any authorized DHCP servers. When a stand-alone DHCP server detects an authorized server on the same subnet, it automatically stops leasing IP addresses to DHCP clients
DHCP and DNS can indeed also be installed without installing Active Directory.
If necessary you can disable the DHCP detection by creating a registry entry:
The following setting will disable the check to see if it's authorized to start DHCP services.

Name: DisableRogueDetection
Data: 1

Please restart the DHCP server service after you have created the registry entry.
