For those running your own test servers, just to let you know that there is a bug in Windows Deployment Services for creating a capture image if you are using Server 2012 R2 with Update. The capture image will fail to load each time. I had to created a Server 2008 R2 machine with WDS and make the capture wim there then bring it over to my WDS server in 2012. This article has other workarounds too but they did not work for me.
