Sorry for the delay in releasing this as it took a bit of time for me to get back to doing it with school and all. When we started making this we hit the size limit on the DVD pretty fast at a puny 4.7 GB limit lol. We cut some of the unnecessary programs out and came up with this Server 2012 R2 copy. I took the time to insert a product key into this upload as well enjoy (this is just for the install and not permanent).
