MSHardenedPolicyEval and/or OSConfig
Hi, basicly the question is: Do they both play nicly together? Is it a "use MSHardenedPolicyEval" or "OSConfig"? Is OSConfig still in active development or will it be retired / deprecated when MSHardenedPolicyEval is GA? While I still really like OSConfig the new MSHardenedPolicyEval looks promising. Best regards, Jan17Views0likes0CommentsWindows Server 2025 hotpaching
Hola a todos, estoy evaluando la actualización de nuestra infraestructura de servidores hacia Windows Server 2025 Datacenter. Me interesa especialmente la funcionalidad de Hotpatching para aplicar parches de seguridad sin requerir reinicios mensuales en los servidores de producción. Mi duda es: ¿Es obligatorio mantener la máquina conectada de forma permanente a Azure Arc para poder beneficiarnos del Hotpatching en un entorno físico tradicional/On-Premises, o existen mecanismos para distribuir estas actualizaciones mediante un servidor WSUS local Microsoft Configuration Manager en entornos aislados? Agradezco de antemano vuestra ayuda.249Views0likes2CommentsAnnouncing Windows Server vNext Preview Build 29667
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 established 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 Windows Server vNext preview builds older than 29531 are not supported. We encourage all Windows Server vNext preview users to perform a clean install using 29531 or later to successfully upgrade to future Windows Server vNext preview builds. 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 the establishment 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 resumed with preview build 29550 or later. What's New Trusted Launch for virtual machines (TVMs) on Windows Server—a security feature you can enable when creating Generation 2 VMs. This initial preview supports TVMs with Secure Boot, vTPM, and vTPM state protection (at rest), managed via PowerShell. ⚠ Not supported in this release: Moving TVMs to another server TVMs in failover clusters or Hyper-V Replica Boot integrity verification TVMs in Windows Admin Center (WAC) Instructions Install the latest ServerInsider preview build.

For more information, please review our blog post: Announcing Trusted Launch for Virtual Machines for Windows Server Insiders | Microsoft Community Hub NVMe-over-Fabrics (NVMe-oF) extends the NVMe protocol—originally designed for local PCIe-attached SSDs—across a network fabric. Instead of using legacy SCSI-based protocols such as iSCSI or Fibre Channel, NVMe-oF allows a host to communicate directly with remote NVMe controllers using the same NVMe command set used for local devices. In this Insider build, Windows Server supports: NVMe-oF over TCP (NVMe/TCP), allowing NVMe-oF to run over standard Ethernet networks without specialized hardware. NVMe-oF over RDMA (NVMe/RDMA), enabling low-latency, high-throughput NVMe access over RDMA-capable networks (for example, RoCE or iWARP) using supported RDMA NICs. For more information, please visit: Introducing the Windows NVMe-oF Initiator Preview in Windows Server Insiders Builds | Microsoft Community Hub 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 A race condition in the TLS hybrid key exchange implementation may cause the LSASS service to crash when hybrid groups are negotiated by a TLS server. To avoid this issue until the fix is released, please disable hybrid groups (X25519_MLKEM768, SecP256r1_MLKEM768, SecP384r1_MLKEM1024) using TLS cmdlets or Group Policy, as outlined here. Server Core Upgrades and AppCompat FOD: Enabling AppCompat FOD after reinstall may fail due to legacy 3rd-party license compatibility issues on Server Core devices. Server Core users may be unable to install the latest AppCompat FOD after upgrading to build 29574. This appears to be limited to Server Core installations with 3rd-party application licenses that fail compatibility checks after upgrade. This will be addressed in a future build. Upgrading from older 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.

HA Print Service Windows 2025 Server
There are two servers running Windows Server, both with the Print Spooler service enabled. They share the same printer queues. I created a CNAME alias named "printcore" pointing to Server01; the client can successfully connect to the printer using the UNC path `\\printcore\hpprincipal`, but if I change the alias to point to Server02, the client's connection to the printer fails. I enabled the Service Principal Name (SPN), but that didn't solve the issue. I need help setting up a High Availability (HA) environment for the print service. Alias: `printcore` (pointing to Server01 and Server02)236Views0likes1Comment

Quick machine recovery (QMR) is now available for Server vNext Insiders to test. This feature enables the recovery of Windows Server devices when they encounter boot critical errors that prevent them from booting. QMR can automatically search for cloud‑based remediations to recover from widespread boot failures significantly reducing the burden on IT administrators when multiple devices are impacted. This supports the goals of the Windows Resiliency Initiative by enabling applicable fixes to be delivered through trusted Windows Update to restore affected devices, helping reduce downtime and minimize manual recovery efforts across enterprise environments. This feature is currently enabled in the latest Server vNext Insider builds for customers to experience test mode. A Group Policy option to enable or disable the feature will be introduced in upcoming builds to provide additional administrative control. To simulate the quick machine recovery experience, use the following commands from an elevated command prompt: Enable test mode: reagentc.exe /SetRecoveryTestmode Configure Windows to boot to Windows Recovery Environment on the next boot: reagentc.exe /BootToRe Reboot your device.The system goes through autoremediation of a simulated crash safely and reboots back to Windows Server.

The current issue is the dependency on Docker and the docker cli for Windows Containers. We would like a native solution from Microsoft for Windows Containers. This would be similar to wslc, but fully compatible for Windows containers. This could be done by leveraging existing Windows container APIs and the containerd container engine for Windows containers.
