This Test Lab Guide Mini-Module describes how to install an additional Active Directory Domain Services (AD DS) forest on the Corpnet subnet. You add a new computer named DC2 and promote
it to act as a domain controller in a new forest named hr.contoso.com. The corp.contoso.com forest and the hr.contoso.com forest do not trust each other. This creates a test lab environment in which you can demonstrate cross-forest scenarios and solutions.
The following figure shows the resulting configuration.
If you are running the base configuration test lab in a virtual environment, you can create snapshots of the virtual machines (VMs) for all of the test lab computers before performing
the following procedures.
First, create a new hr.contoso.com DNS domain on DC1, which will be acting as a DNS server for the new computer.
Next, install Windows Server 2008 R2 Enterprise Edition as a standalone server on a new computer.
Next, configure the TCP/IP protocol with a static IP address of 10.0.0.250 and the subnet mask of 255.255.255.0.
Next, configure DC2 as a domain controller for the hr.contoso.com domain.
Next, create a HRUser1 account, equivalent to the User1 account in the CORP domain.
If you are running this test lab in a virtual environment, you can create snapshots of the virtual machines (VMs) for all of the test lab computers to save this configuration.
