The Windows Server 2012 Base Configuration test lab consists of up to five separate computers on two separate subnets:

• The Corpnet subnet contains the DC1, APP1, and EDGE1 (optional) computers
• The optional Internet subnet contains the INET1 and EDGE1 computers

The CLIENT1 computer can connect to either subnet. The following figure shows the base configuration test lab (click on it for a larger version).

This figure shows the computers and their connections to the subnets using a hub or switch. You can implement this configuration using physical computers and switches, virtual computers and switches, or a combination of physical and virtual components.

If you are using Windows Server 2012 and the Hyper-V server role for your virtualization solution, you can configure the base configuration in Hyper-V on a single server as shown in the following figure (click on it for a larger version):

The key elements of this configuration are the following:

• All five computers (DC1, APP1, CLIENT1, EDGE1, and INET1) are virtual machines running on the Hyper-V server.
• The Corpnet subnet is implemented as the Corpnet virtual switch.
  • DC1, APP1, and EDGE1 are connected to the Corpnet virtual switch.
• The Internet subnet is implemented as the Internet virtual switch.
  • EDGE1 and INET1 are connected to the Internet virtual switch.
• CLIENT1 can be connected to either the Corpnet or Internet virtual switches.
• The Hyper-V server has at least one physical network adapter that connects to your organization intranet and the Internet. You can use this connection to connect a base configuration test lab computer to the real Internet (rather than the Internet subnet), for example to install software or updates.

To build out the Corpnet subnet in Windows Server 2012 Hyper-V, do the following:

1. Create a private virtual switch named Corpnet. For the steps to do this, see Creating a new virtual switch.
2. Create a new virtual machine named DC1 that is connected to the Corpnet virtual switch. For the steps to do this, see Creating a new virtual machine.
3. Create a new virtual machine named APP1 that is connected to the Corpnet virtual switch.
4. Create a new virtual machine named CLIENT1 that is connected to the Corpnet virtual switch.
5. Follow the instructions in the “Steps for Configuring the Corpnet Subnet” section of the Test Lab Guide: Windows Server 2012 Base Configuration. To install Windows Server 2012 or Windows 8 on a virtual machine, see Installing an operating system on a new virtual machine.

To build out the Internet subnet in Windows Server 2012 Hyper-V, do the following:

1. Create a private virtual switch named Internet.
2. Create a new virtual machine named EDGE1 that is connected to the Corpnet virtual switch. Add a network adapter to EDGE1 that is connected to the Internet virtual switch. For the steps to do this, see Adding a network adapter to a new virtual machine.
3. Create a new virtual machine named INET1 that is connected to the Internet virtual switch.
4. Follow the instructions in the “Steps for Configuring the Internet Subnet” section of the Test Lab Guide: Windows Server 2012 Base Configuration.
