Script Error When Upgrading ADK To Windows 11

You may seen the above error when PXE booting images under the new Windows PE edition for Windows 11. Yes, frustrating right! Well this is what I did to fix the issue. Depending on how many WDS/MDT servers you have you may have to follow this multiple times.

First you will want to open a new Command Prompt “CMD” window in Administrator mode. Type in the following reg.exe add”HKLM\Software\Microsoft\Internet Explorer\Main” /t REG_DWORD /v JscriptReplacement /d 0 /f

Next Backup this C:\Program Files\Microsoft Deployment Toolkit\Templates\Unattend_PE_x64.xml file. Then edit the file with the code below and finally regenerate the entire WIM image. If you have more than one server you will have to follow these instructions again.

<unattend xmlns="urn:schemas-microsoft-com:unattend">

        <component name="Microsoft-Windows-Setup" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="">

MDT Error 0xc0000001

In the midst of attempting to deploy out a new Windows Server 2019 installation I came across a new issue. As mentioned in the title of this quick block. My remote virtual machine posted the error 0xc0000001 which was odd since I was able to PXE call from my onsite domain controller (DC02) and start to load the boot file config.

After some research and a few cups of coffee I found that the resolution to this issue was the Enable Variable Windows Extension. To fix this follow the instructions below…
1. Open your Windows Deployment Services app or WDS
2. Right click on your WDS server in the left pane
3. Left click on Properties
4. Click on the TFTP tab within the properties window
5. Uncheck Enable Variable Windows Extension
6. Lastly Reboot your WDS Server

If you followed all the steps above correctly you should be able to PXE boot your VM from MDT now. Enjoy!
