Below is a link where you can download the scripts and directory structure that I used in the session No Lab, No Problem! Building the Essential Lab Environment Using Microsoft Technologies (WIN-B365) that I presented at TechEd North America 2014. For some reason they did not get uploaded to the TechEd Schedule Builder, so I apologize for the inconvenience. After downloading the zip file, extract it to C:\Lab_Software. Inside each of the folders there is a read me text file that lists that contents that should be placed in each folder.
Good info in your lab last Wednesday. Bought two PowerShell books from the TechEd store and looking forward to using PS a lot more, starting with your virtual lab!
