Windows Server 2022, Hyper-V, Failover cluster We have a Hyper-V cluster where the hosts reboot once a month. If the host being rebooted has any number of VMs running on it the reboot can take hours. I've proven this by manually moving VM roles off of the host prior to reboot and the host reboots in less than an hour, usually around 15 minutes. Does anyone know of a powershell script that will detect clustered VMs running on the host and move them to another host within the cluster? I'd rather not reinvent this if someone's already done it.159Views0likes3CommentsAnnouncing Windows Server vNext Preview Build 29641
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 [NEW] Preview Build 29641 extends the expiration date of the preview builds into 2027. We're excited to announce 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 Quick Machine Recovery available in Windows Server vNext Insider Previews. 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: 1. Enable test mode: reagentc.exe /SetRecoveryTestmode 2. Configure Windows to boot to Windows Recovery Environment on the next boot: reagentc.exe /BootToRe 3. Reboot your device. The system goes through autoremediation of a simulated crash safely and reboots back to Windows Server. For more information, please review Quick machine recovery (QMR) and Windows Resiliency Initiative. When providing feedback using Feedback hub, please select QMR from the Recovery and Uninstall category in the app. 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.

Unable to Uninstall Security Update (KB5094128) on Azure Hosted Windows Server 2022 VM
Hi All, I'm building up a system on Azure of Windows Server 2022 VMs for a PoC. Each Windows Server 2022 VM has been created using a company hardened golden image. After configuring the VM successfully, I am unable to run a software. Through research, the solution to run the software is to uninstall 'Security Update for Microsoft Windows (KB5094128)'. The issue is that I cannot uninstall the update normally. I have looked up various solutions and the following have been unsuccessful: Attempt #1 Powershell (Admin): sfc /scannow wusa /uninstall /kb:5094128 Result: Error 0x800f0905. Attempt #2 Powershell (Admin): Dism /Online /Cleanup-Image /CheckHealth Dism /Online /Cleanup-Image /ScanHealth Dism /Online /Cleanup-Image /RestoreHealth wusa /uninstall /kb:5094128 Result: No corruption detected, error 0x800f0905. Attempt #3 Powershell (Admin): net stop wuauserv net stop cryptSvc net stop bits net stop msiserver ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 catroot2.old net start wuauserv net start cryptSvc net start bits net start msiserver wusa /uninstall /kb:5094128 Result: All services started and stopped. Error error 0x800f0905. Attempt #4 Windows Update Troubleshooter: Running the windows update troubleshooter gives the following output. The event viewer is suggesting there is a corrupted file error, but as seen above nothing is wanting to remove that file. Does anyone have any other options they could suggest? Or has anyone had success with this issue before? Is it a lost cause as we have to use company hardened golden images? Any suggestions would be appreciated!81Views0likes2CommentsRemoval of old CA server stale data
Hi, I'm rebuilding some DC's and figured I'd tidy everything up before doing so as I've come into this with a messy environment. from this, I found an old Trusted Root CA, the certificate authority server was decommissioned in 2021 and all certificates have had an expiry date from 2021. its still being pushed out to domain devices such as servers and desktops. I tried running the 'certutil -dsdelca' command however this comes back with invalid command. I guess the best option is just to remove the class objects from the ADSI edit? as there is a class in AIA, CDP, Certification Authorities, KRA with the certificate name85Views0likes3CommentsRemote Desktop Web Audio Not Passing (Correctly)
Hello! I manage an RDS farm (WEB/GW, CB, DB, HST etc) at work, and it's been working great aside from Audio Passthrough. Clients will connect to the RD Website and then launch a remote app of their choosing. However, when the client is on the remote app PC and uses their audio (via an app or just using mmsys.cpl) the remote session will just freeze and be unusable. All RDS Infra is on at least Win. Server 2019+. All GPO Settings have been properly configured, as well as collection, CAP/RAP, and browser settings. I have confirmed launching RDP (mstsc.exe) session from my local laptop to the remote app PC (through the HST) does work without any issue, so I am led to believe there is something wrong with RD Web. RD Web Client Pkg is on the latest version. Any advice is greatly appreciated as I am banging my head against the wall trying to get it to work with RD Web.

Hi all, I have 1 Server Cluster made up of 3 Server 2022 Hosts on which there is a large number of VMs running on Hyper-V. The typical process for accessing the VMs has been through Windows Admin Center, which is hosted on one of the VMs in the cluster. Around 1 week ago, it was no longer possible to connect to the VMs through Windows Admin Center as an infinite loading screen was presented. Sometimes, the following error shows up in VMConnect: The cluster and servers are still connected to WAC and all the VMs that are expected are present on WAC. Since then, the following things have been attempted: - Restart all servers - Rebuild WAC on Current VM - Build WAC on Fresh VM with the same and different network configuration, using current (2606) and previous (2511) versions of WAC - Build WAC on one of the hosts All these attempts result in the same error as seen before. Has anyone experienced this issue before? Or does anyone have any advice? Thank you in advance!Solved417Views1like11CommentsWindows integrated CA - Certificates are not usable for any browser NET::ERR_CERT_INVALID
Hi all, a Windows integrated CA on Windows Server 2025. I have published web server certs on IIS (should be for Exchange on prem). Did this couple of times. But all Certificates released by this CA are not usable for any browser: NET::ERR_CERT_INVALID. Tried with different browser and different server. Cert is valid surely. root cert also in place. error detail: "normally uses encryption to protect your information. When Google Chrome tried to connect to localhost this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be localhost, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged. You cannot visit localhost right now because the website sent scrambled credentials that Google Chrome cannot process. Network errors and attacks are usually temporary, so this page will probably work later." Any hints what is wrong? Thanks for hints Gernot71Views0likes4CommentsTSplus as an alternative to RDS without paying RDS license fees to microsoft
Hello, We are evaluating whether to use TSplus (https://www.terminalserviceplus.eu/) as an alternative to Microsoft RDS/Terminal Server. According to TSplus we can not install or uninstall the RDS role, so we do not use RDS CALs and use TSplus CALs. This way it would not be necessary to pay for Windows Remote Desktop licenses. Is this correct? I can't find any information from Microsoft about it reading documentation. As I see it is correct that using TSPlus without installing Microsoft RDS it would not be necessary to pay Remote Desktop licenses. Could someone confirm me that it is so?28KViews0likes19CommentsResize-StorageTier / Expand Volume on Windows Server 2025 Campus Cluster does not work

Hello, I have a virtual machine running Windows Server 2019 Datacenter with Active Directory, and all users access it via RDP. No specific access configurations have been set up; I wanted to know if it is possible to check how many times a specific user has connected and from which IP address—is that possible? Also, I wanted to ask if it is possible to determine whether a specific user copied files to their local PC using copy/paste during a session.
