If, like you say, another physical machine can obtain an address from the Windows Server 2012 DHCP running as Virtual Machine then DHCP service is working fine.<br />
That also means that DHCP VM has to be configured with and connected to at least one External type Virtual Network.<br />
You should check if both DHCP VM and Windows 7 VM are configured to use the same Virtual Network. <br />
In Windows 7 VM Settings, Network adapter should be connected to the same Virtual network as DHCP VM is.<br />
Double check whether Windows 7 VM NIC is configured to obtain an address automatically.

I've configured a Windows 2012 Hyper v system with 2 guest OS(s). 1 is a Windows 2012 DC with DHCP services. The other is a Windows 7. &nbsp; &nbsp;I can't get the Windows 7 to obtain an IP address off of the DHCP server vm. Even though I have another physical machine that can get an address without any problems. &nbsp;Any ideas?

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.
