Let’s step through the Test Lab Guide for setting up the Windows Server 2012 base configuration. The Windows Server 2012 Base Configuration test lab guide, or TLG, creates a standard infrastructure upon which other TLGs can build. This Base Configuration uses computers running Windows Server 2012 and Windows 8. Note that there is a separate base configuration TLG for computers running Windows Server 2008 R2 and Windows 7. Here is the Remote Access TLG stack for Windows Server 2012, an example of a stack that builds upon the Windows Server 2012 base configuration. This stack configures and then demonstrates DirectAccess and remote access VPN connectivity in Windows Server 2012 and Windows 8. Now, let’s build out the Windows Server 2012 base configuration test lab. The base configuration test lab consists of two subnets: one named Corpnet and one named Internet. You start with the Corpnet subnet and add the computer named DC1. You then configure it as an Active Directory Domain Services, or AD DS, domain controller for the corp.contoso.com domain, a DNS server, a DHCP server, and then add a User1 account. In Step 2, you add the computer named APP1 and join it to the corp.contoso.com domain. You then install the Web Server (IIS) server role, and then configure APP1 as a file server. In Step 3, you add the computer named CLIENT1 and join it to the corp.contoso.com domain. You then verify access to the Web and file share resources on APP1. In the next section, you configure the Internet subnet. This is optional as some TLG stacks do not require it, but it is recommended because a different TLG stack might require it or you might need it to experiment with your own Internet-based scenarios. In step 1, you add a computer named EDGE1 and join it to the corp.contoso.com domain. Note that EDGE1 is not configured to perform any routing between the two subnets or any remote access VPN or proxying services. These capabilities are left to other TLGs. In step 2, you add a computer named INET1 and configure it as a Web Server, a DNS server, a DHCP server, and with additional settings so that CLIENT1 detects the Internet subnet as the real Internet. Now you have both subnets and CLIENT1 can move from the Corpnet subnet to the Internet subnet and back again, simulating a roaming computer. Snapshot these computers so that you can always return to this initial configuration. Now you are ready to build additional TLGs that rely on this base configuration or experiment on your own. You can also extend this Base Configuration using two different test lab mini-modules. You can add a Homenet subnet using an additional Windows 8-based computer named NAT1 and an additional switch, simulating a typical home environment that uses a network address translator, or NAT, to connect to the Internet. You can also add a Corpnet2 subnet through an additional network adapter on DC1 and an additional switch, simulating a multi-subnet intranet environment.
