Hello, So im currently an IT Apprentice and thought that I should try out WDS, and a friend linked me to a video that worked for him. Here is a link to the video https://www.youtube.com/watch?v=6Bllzv_qayM . ill try to explain my problem to the best of my ability. Fyi Im using Windows server 2012 R2

So I Installed and configured the WDS and DHCP role on the server. installed the ADK windows 10 and MDK 2013. I did everything in the video. However when I tried to deploy the image I uploaded I had to determine the path to the boot folder, and then I have to type in the credentials, and after I typed in the credentials it just asks me to do it again. How can I fix this? If you need some more information just tell me :).
