The file Microsoft_Server_InsiderPreview_LangPack_FOD_29531.iso is missing language packs.
Is it difficult to put these language packs in Microsoft_Server_InsiderPreview_LangPack_FOD_29531.iso?

Account blocked downloading any Insider ISO
Same basic message as the Google Fiber user, however, I know what caused my account to be blocked. I did not approve a Firewall request for Webview2 while using Server 2022 and Duck Browser (you know which one as I am not approving of nor recommending a non-MSFT issued browser here) to Download the ISO for Vnext on the Server Insider's Download page. I am still able to log into the page, select a build, choose my language, and I get the error after clicking Confirm. It also happened in Edge and on my cell phone using Cellular and it's proprietary browser. I installed 26534, and though it did allow me to attach my insider id to it, it would not dl a newer build, nor any Insider build for Windows 11 either. The page simply says to contact Microsoft support if you feel you got this in error. Of course, that would not accomplish anything except confuse some MSFT contacted Tech support and possibly incur a fee for me. You have my account info. Any help clearing it would be appreciated.

DNS DOH and DOT Server 2025
Does anyone know if Windows Server 2025 is planning to support native DNS over HTTPS or DNS over TLS? As of now, windows clients can be configured to support this, but MS DNS is not DOH or DOT compliant. I am just wondering if this is being considered or if it is on the roadmap. Thanks!

Windows Server 2025 arm64
Will there be an official release of Windows Server 2025 arm64? If so when? The last Canary Cannel release worked fine on a M1 (or higher) Apple computer with the use of Parallels.

NTFS permissions are partially not working.
Participant A is sometimes unable to see Participant B’s files. The issue can be resolved by clicking the option: "Replace all child object permission entries with inheritable permission entries from this object." However, the problem keeps reappearing. Windows Server 2022 Datacenter (VMware 7.1), formatted as NTFS.

Announcing Windows Server vNext Preview Build 29531
Hello Windows Server Insiders! Today we are pleased to release a new build of the next Windows Server Long-Term Servicing Channel (LTSC) Preview that contains both the Desktop Experience and Server Core installation options for Datacenter and Standard editions and Azure Edition (for VM evaluation only). Branding remains Windows Server 2025 in this preview - when reporting issues please refer to Windows Server vNext preview. Build 29531 establishes a new Server preview baseline build. Please perform a clean install of Build 29531 (or later) using the installation media linked below. Please note: Upgrades from earlier Windows Server vNext preview builds are not supported. We encourage all Windows Server vNext preview users to perform a clean install to reliably continue in the Windows Server vNext preview program. While upgrades from earlier Windows Server previews (Build 26525 and older) are not technically blocked by setup.exe, a number of known issues have been identified related to upgrades necessitating a release of a new baseline build for our Server vNext Preview Program. The new baseline build (29531) will not be Flighted due to upgrade issues. Flighting support will resume with future vNext preview releases. What's New [NEW] ReFS Boot is enabled for Windows Server vNext preview builds. Known Limitations ReFS Boot systems create a minimum 2GB WinRE partition. When WinRE cannot be updated due to space constraints, the system may disable WinRE. Disabling WinRE does not remove the partition. If the WinRE partition is deleted and the boot volume is extended over it, this operation is unrecoverable without a clean install. For more information, please visit: Resilient File System (ReFS) overview | Microsoft Learn Feedback Hub app is available for Server Desktop users! The app should automatically update with the latest version, but if it does not, simply Check for updates in the app’s settings tab. Known Issues Upgrading from earlier builds of Windows Server vNext previews (26525 or older) are not supported. Please perform a clean install of build 29531 or later. Users may experience failures when attempting to upgrade from earlier previews (build 26525 and older). VMs may fail to upgrade or start after upgrade from older preview builds impacting live migration and failover cluster scenarios. Download Windows Server Insider Preview (microsoft.com) Flighting: The label for this flight may incorrectly reference Windows 11. However, when selected, the package installed is the Windows Server update. Please ignore the label and proceed with installing your flight. This issue will be addressed in a future release. Available Downloads Downloads to certain countries may not be available. See Microsoft suspends new sales in Russia - Microsoft On the Issues. Windows Server Long-Term Servicing Channel Preview in ISO format in 18 languages, and in VHDX format in English only.  Windows Server Datacenter Azure Edition Preview in ISO and VHDX format, English only. Microsoft Server Languages and Optional Features Preview  Keys: Keys are valid for preview builds only  Server Standard: MFY9F-XBN2F-TYFMP-CCV49-RMYVH Datacenter: 2KNJJ-33Y9H-2GXGX-KMQWH-G6H67 Azure Edition does not accept a key. Symbols:  Available on the public symbol server – see Using the Microsoft Symbol Server.  Expiration: This Windows Server Preview will expire September 15, 2026.
