b26085 – Windows Server 2025 Domain Controller fail to deploy via DSC
Hi there,
I am trying to deploy mslab using Windows Server 2025 preview.
I believe Jaromir as maintainer of mslab opened an SR. In result he updated the code some PS DSC Modules.
Still the deployment of the domain controller template will fail during first boot.
This is not specific to b26085, this one is troubling for since WS2025 insider, so it never worked with this branch.
Repro steps
Install Windows Server 2025 b26085.1 on a physical machine and enable Hyper-V
Download and extract mslab
https://github.com/microsoft/MSLab/releases/tag/v24.04.1
run the mslab scripts in order
1_Prereq
2_CreateParentDisks
> select Windows Server 2025 ISO b26085 (WS 2022 ISO will work)
> skip the MSU dialogue
Domain Controller VM gets created from parent disk image
First boot will fail with following error
Question:
What could be reasons it keeps failing. We have no clue / pointers and imho it would be expected and necessary that mslab works with WS2025, too.
Who at Microsoft could afford time to repro and looking into that?
As mslab is also used by Microsoft, I hope anyone could spare time to investigate (with Jaromir and/or me). I personally can spare time for that investigation.
Thank you very much in advance!
