In reply to matt.

I’m also having the same issue. Changing block sizes to all the recommended, checked and unchecked variable windows extension – nothing works – server 2016
Even changed the values through bcdedit – still nothing . did you fix it in the end?

Uncheking “Enable Variable Windows Extension” worked for us as well. Thanks!

Uncheking “Enable Variable Windows Extension” worked for imaging WDS wim files in Server 2012 but not for WDS does not start. Still going to try figure this out on Server 2019.

Thanks for the help guys

The solution worked for me too.

The culprit (in our case) was the March 2019 Cumulative Update which has a known issue which affects PXE
