This is the scripted/quick walk-through which lets you install your multi-server Windows Server 2012 Domain Environment. Install time for the two server domain takes less than 30 mins.
You can use the environment in order to test software or study the software. You could use this procedure as a guide or example for real-life installations too, assuming you own the correct software licenses.
This is clean domain installation, i.e only the most necessary steps are covered to install a functioning 2 Server domain. ( see below for more info )
