Issue with winlogon on Remote Desktop Services:
We are investigating intermittent session establishment failures on Windows Server 2019 servers used as CyberArk PSM / RDS hosts. At unspecified intervals, new privileged sessions fail to establish or are disconnected during the initial session/logon phase. The issue is intermittent and affects new sessions. Existing sessions may continue to work. The strongest and most consistent correlation identified so far is: Microsoft-Windows-TerminalServices-LocalSessionManager/Operational – Event ID 36 Application / Microsoft-Windows-Winlogon – Event ID 4005 We observed that TerminalServices-LocalSessionManager Event ID 36 can occur without a subsequent Winlogon Event ID 4005. However, every observed Winlogon Event ID 4005 is correlated with TerminalServices-LocalSessionManager Event ID 36 in the same incident window. This suggests that Event ID 36 is a consistent precursor or required condition for the Winlogon 4005 cases. Environment Operating system: Windows Server 2019 Role: CyberArk PSM / RDS session host Issue type: intermittent failure during new RDP/PSM session initialization Impact: affected users cannot establish privileged sessions or are disconnected during session startup Similar issue exists on previous windows server 2012 R2 and was fixed : August 16, 2016 – KB3179574 (During virtual channel management, a deadlock condition occurs that prevents the RDS service from accepting new connections.) https://support.microsoft.com/en-us/topic/august-2016-update-rollup-for-windows-8-1-and-windows-server-2012-r2-d472b5d5-4b3a-8e6e-c22a-f62fed604caf I'm looking forward for any ideas how to resolve this issue. Many thanks!!Windows Server 2025 DC — LSASS handle leak identified via WinDbg — authz!AuthzpDeQueueThreadWorker
Hello All!! Im having a problem, LSASS crashes on a Windows Server 2025 Domain Controller, I identified what appears to be the root cause using WinDbg memory dump analysis. Sharing this hoping someone else has seen it or Microsoft can confirm. The Problem LSASS handle count grows continuously over time and eventually crashes with a 0xC0000005 access violation (Event ID 1015). After a reboot the cycle repeats. The growth rate correlates with authentication load and faster during peak hours, slower overnight. WinDbg Dump Analysis Captured LSASS dump at high handle count and ran !handle 0 f: Token handles: overwhelmingly dominant Everything else: negligible Every leaked token shows: GrantedAccess: 0x8 (TOKEN_QUERY only) PointerCount: overflowed to negative integer Running !findstack authz 2 shows multiple worker threads all sitting in: authz!AuthzpDeQueueThreadWorker What Was Tested And Eliminated Stopped or disabled each individually and measured handle growth rate — zero meaningful difference from any: - Antivirus (all components) - Backup software - Application services - VSS snapshots - Hardware management agents etc.. Environment OS: Windows Server 2025, fully patched with the latest updates including April LSASS update. Role: Domain Controller DNS PAM: Not active. Conclusion Token handles are opened with TOKEN_QUERY access inside authz!AuthzpDeQueueThreadWorker and never released. Reference counter overflows to negative integer. Growth rate scales directly with authentication load. Current workaround: reboots during off hours. Has anyone else seen this pattern on Windows Server 2025? Is there a known fix or Microsoft acknowledgment for this specific authz token handle leak?
Windows Server 2025 Failover Cluster Live Migration Issue
Hi Everyone, I am facing an issue in a Hyper-V Failover Cluster environment where Live Migration intermittently fails due to a service logon-related problem. The environment was previously working normally, but now whenever we attempt to Live Migrate a VM between cluster nodes, the migration fails unless we manually run “gpupdate /force” on the Hyper-V host first. After running gpupdate /force, the migration works temporarily, but the issue returns again during the next migration attempt. This makes it appear that some policy or permission is not being applied consistently on the cluster nodes. During troubleshooting, I attempted to add “NT VIRTUAL MACHINE\Virtual Machines” to the “Log on as a service” policy under Local Security Policy > Local Policies > User Rights Assignment. However, the account does not appear or resolve in the Object Picker when trying to add it manually. At this stage, I am trying to understand whether this is related to a domain GPO overwriting local policy settings, a Failover Cluster permission issue, or something specific to Hyper-V virtual machine accounts. Has anyone encountered a similar issue where Live Migration only works after running gpupdate /force? Also, is there a correct method to add “NT VIRTUAL MACHINE\Virtual Machines” to the “Log on as a service” policy, or should this permission already exist by default on Hyper-V hosts? Any guidance or recommendations would be greatly appreciated.Secure Boot update still pending on deadline day
After checking the registry keys on 2x VMs which run services for a number of important customers I found they both have: UEFICA2023Error 2147942750 Apparently this means they're pending a reboot. https://blog.mindcore.dk/2026/04/secure-boot-certificate-update-intune/ I can't reboot the VM inside working hours, can they be rebooted after the deadline or do I need to disable Secure Boot on the VMs? I'm concerned I'll have to disable Secure Boot before they're next rebooted for Windows updates.Server 2025 to server 2022 downgrade keys
Hello, We bought licenses with these part #'s MFR# P73-08495 and MFR# EP2-25187 which, according to searches on the internet, have downgrade rights. We need to get downgrade keys for server 2022 standard. Our reseller referred us to Microsoft for this. Could someone help? The activation portal does not give us an option to do this and a microsoft support agent told us to make a post here which seems weird to us. We don't know why they couldn't help us via the phone. Thanks
Write to workgroup fileserver from AzureAD joined device.
Hi, We currently have a situation where we are trying to install a program locally, but we want some of the data files (master data for projects, company settings for the most part) to be stored on a fileserver. The installer allows for this change to set UNC path to the share manually, and in our case recommends doing that. The problem we are facing occurs when trying to go on with the installation, the problem reports back that write-protection is enabled. I have the share mapped as a nettwork station, and can create folders/files through explorer. But I think the issue here is that the share mapped using the "Connect with different credential" option, which is required since the share is on a server in a workgroup and the client I'm using is joined to AzureAD. And when i run the installer for the program it is ofcourse ran with my azure user (local administrator), and I guess it tries to write to the UNC path with that user ofcourse. Is there any way i can let the program write to the share without it being to much of a security risk? The same program also has a nettwork license installed on a different workgroup server. I also had to add local users to that server and do some DCOM permission tweaking for that to work. For the license part i can authenticate with the local server user, but thats not an option when trying to install with UNC path for the file/folder structure.Active directory allowing old and new password after reset
We are using windows 2019 server and once password is reset (before expired), we see a behavior that old password is valid for 5mins after password reset. Our replication delay is 15 seconds and we haven't set registry key OldPasswordAllowedPeriod. By documentation https://learn.microsoft.com/en-us/troubleshoot/windows-server/windows-security/new-setting-modifies-ntlm-network-authentication it is mentioned that if OldPasswordAllowedPeriod is not set, default will be 60mins. So where is this 5 mins configured?in-place upgrade fails from b29574 to latest vnext b29595

While I greatly appreciate the decision of vbscript / cscript / wscript removal, with security and hardening in mind – I would also appreciate if Microsoft could be actively using the vNext release channel, preparing for feature removal. With this blogpost, I am sharing my point of view on the state of dependencies I am seeing in this regard, focusing on a way forward towards the full removal of vbscript. My findings show, that there is a quite some action required, and this stands a bit contrary to the announcement, Microsoft intends removing the optional feature of vbscript by default with the upcoming release - anticipated by fall 2027. Given my lessons learned from Secure Boot CA2023 exchange initiative, Microsoft guidance, foremost PowerShell based scripts, tooling and dashboards have been released quite late, looking at the timeline, considering the impact and scale customers had to deal with, and consequences for their security posture if they are not ready and done, with first certificates to expire soon. Taking this learning into account and and projecting it to vbscript deprecration I come to the following conclusion: SMB customers, enterprises, Microsoft Products, see below, are required to be updated or replaced, in order of adopting this change. I believe there is quite some communication and learning curve required for users, admins, enterprises and OEMs in adopting the implicated change and including changed workflows and automation processes. Looking forward to the next Windows Insider and esp. Windows Server Insider vNext builds! Both Windows Insiders and Windows Server Insiders, also including ISV and OEMs may assist in reviewing and validating the new workflows required - assuming vbscript deprecation is in effect, as planned. Without further ado, I am sharing my observations in regard to VBScript deprecation. I will try to keep this blogpost updated as soon I am aware about public facing changes. Third-Party AMD Chipset drivers so far is one of the major non MSFT related blockers. Suggestions: Microsoft should initiate talks with AMD and other ISV and OEMs fixing their dependencies, also offering other solutions, see below. Currently AMD Chipset drivers silently using vbscript calls checking for OS and HW platform compatibility. The installer fails when vbscript optional feature is removed. OEM, ISV and Enterprise Potentially affected: expected dependencies for imaging, deployment and management workflows. Related or unrelated to Microsoft products. LOB apps custom Office Integration logon and logoff scripts setup and installers Recommendation: Please observe vbscript related events in Windows Event Viewer at scale using PowerShell, Remoting or Windows Event Subscriptions: VBScriptDeprecationAlert Event ID 4096 VBScript is scheduled for deprecation. Our telemetry indicates that your system is currently utilizing VBScript. We strongly recommend identifying and migrating away from any VBScript dependencies at the earliest. The following process has been detected as using VBScript. The associated process tree and call stack are provided below to assist in identifying the scenario in which VBScript was invoked. Microsoft Windows Server and Client OS affected: slmgr.vbs / printer management vbscripts / product activation logic and UX, setup.exe, slui.exe Office 2024 LTSC affected: slmgr.vbs / ospp.vbs / Office deployment toolkit / product activation logic Microsoft has placed a new PowerShell based script into the respective OSPP folder. This script however is rather offering on checking licensing and cannot activate the Office product at this time. Microsoft 365 Business, Enterprise, Home, Family Affected: ospp.vbs despite being subscription based will also trouble with activation once vbscript is removed Sconfig Related to product activation. no changes so far, relies on external changes. The script itself is safe to comply with the change, now it has been reworked and updated using PowerShell , starting Windows Server 2022. WinRM Affected: the whole WinRM configuration command, e.g. winrm qc Windows Server Roles and Features: KMS / ADBA Potentially affected as they rely on slmgr for adding and removing CSVLK keys. Windows Server Roles and Features: IIS legacy IIS extension management. Windows Server Roles and Features: WSUS related deployment and configuration scripts. System Center Products incl. ConfigMgr there might be depencendies for OS deployments in regard to OS imaging. ADK, esp. Windows Imaging Tools and VAMT 3 potentially affected. Need to adopt changes in regard to activation and other operations. Suggestions: Recommending all these scripts being converted using Claude or Copilot from vbscript to PowerShell. Providing a serviceable PS modules, especially for printer management, product activation, which enables enterprises to automate their activations and printers, even though Microsoft is going to remove vbscript. The modules should be improved for existing day two adminstration tasks and workflows. slmgr, in particular, had some nuances that were tedious such as identifying and removing (stale) activation keys. Existing tools like slmgr and other will not work well in remoting. They do something but their interactive parts and outputs are reserved for interactive user sessions. Example: you can use slmgr in a remote PowerShell session for installing and activating a key but therer is no result return to the shell. Combining slui.exe and slmgr.vbs into aforementioned improvements in functionality and syntax. Consider support for PowerShell 7 in WinRE and Offline Setup phase. Many thanks for your consideration!

Hi Community, I installed my first Windows server to learn about the server and Active Directory. I installed Windows Server 2022. I configured a static IP and disabled IPv6. Then I installed Active Directory/DNS. After the reboot, the system is up, and I can access the internet and ping hosts. However, there is a world icon (No internet access) instead of a computer icon (internet access). In the static IP config, it replaced the DNS with 127.0.0.1, I know it'll use the local host as DNS. When I click on Network & Internet settings and Troubleshoot, I see an error 'DHCP is not enabled for "Ethernet"'. The only way it goes away is if I change the static to automatic. How can I fix this issue? Thanks, Also, I added forwarders such as 1.1.1.3 and 1.1.1.2 to DNS.
Hostname Character Limit
Still being limited to 15 characters for hostnames in 2019 is very upsetting. In an age where we are deploying servers in multiple data centres, whether that be on premise or in the cloud and having multiple environments as well means trying to come up with sensible hostnames in just 15 characters is basically impossible. I’m sure I am not the only person who is frustrated by this limit and would very much like it if Microsoft was to revisit this limit and increase it to bring it in line with the wonderful limit our Linux friends enjoy.
SCCM- Upgrade from 2409 to 2509 WSUS timeout issue
Had a working task sequence on 2409 that performed software updates at the end of the task sequence. Upgraded to 2509 - I get a timeout issue when getting to that point on the task sequence. Ive performed maintenance on the WSUS Server, (obsolete, expired etc) I removed the Software Update Point - and re installed it selected the Products of Server 2016,2019, server operating system 21h2 , Windows 10 1903 or later and Windows 11. rebooted both the SCCM and SQL Server. after doing the above but the HRESULT 0x80244010 still persists. "Exceeded max server round trips" — client couldn't retrieve all updates in one cycle. Software centre updates in the OS seem to be unaffected or unknown if clients are affected, only in a task sequence this occurs. Blog posts refer to older items, what would cause this to fail after a upgrade from 2409 to 2509? AI help repeats about reducing metadata and updates but for weird reason i keep getting 700+ updates for the above categories!Event 4768 for one user
Hi all, We have two domain controllers running server 2019 with Domain Functional Level 2016. We have one user who has been with us for almost a year, and they were suddenly getting a message in the last week that username or password were incorrect even though we confimed they were not. They were able to initally switch to another user and re-enter their username and log in, but now it won't allow that. On the domain controller I see events for the user Audit Failure 4768 with Result Code 0x6. This result suggests the username doesn't exist which isn't true. The account isn't being locked. Has anyone seen this before and know what the issue might be? thanks jmServer flighting not being offered on 29595 on 3 VMs

Windows Crash During NVMe Over TCP Disk Disconnect
While evaluating the Windows NVMe Initiator, we have observed that disconnecting an NVMe disk frequently results in a Windows system crash. This occurs during the disconnect operation and appears to be reproducible in our test environment. Questions: Has anyone else encountered similar behavior? Are there any known issues related to NVMe/TCP disconnect handling? Are there recommended troubleshooting steps, logs, or diagnostics that we should collect to help identify the root cause? Any insights would be greatly appreciated.Multiple Namespace Detection in Windows NVMe Over TCP Initiator
We are evaluating the Windows NVMe Initiator and have observed an issue with namespace handling. Our NVMe subsystem contains multiple namespaces. When we connect to the subsystem over TCP and establish connections to all namespaces, they are all shown as connected under the controller. However, only one namespace (shared block device) is exposed and accessible within Windows. Based on our testing, it appears that the initiator may be mapping only the first namespace associated with a given Friendly Name. We were able to connect another subsystem, whose friendly name was different. Questions: Is support for multiple namespaces within a single subsystem currently available in the Windows NVMe Initiator? If so, are there any configuration requirements or known limitations related to namespace discovery and mapping? Is the initiator expected to expose all connected namespaces as separate disks within Windows? We would appreciate any guidance or clarification on the expected behavior.
