AOVPN / Reasoncode 16
We have an always on vpn configuration. This worked fine till few months ago, users can't get connected anymore. After reboot of NPS server, all works fine for some time (random, sometimes 1 day, 2 days, 1 week), till the users can't get connected again. Reboot of nps server solves it. When users can't connect, I see an event on NPS server with reason code 16 Network Policy Server denied access to a user. Contact the Network Policy Server administrator for more information.

Reason Code: 16 Reason: Authentication failed due to a user credentials mismatch. Either the user name provided does not map to an existing user account or the password was incorrect. As said, reboot of nps solves issues temporary. Already installed new nps server but same issue. Any suggestions where to check ?

Add support for sha-2 and sha3 in Supported Kerberos Encryption Types
https://techcommunity.microsoft.com/t5/core-infrastructure-and-security/decrypting-the-selection-of-supported-kerberos-encryption-types/ba-p/1628797 https://web.mit.edu/kerberos/krb5-devel/doc/admin/enctypes.html#enctype-compatibility It seems like `aes128-cts-hmac-sha256-128` and `aes256-cts-hmac-sha384-192` are supported by other Kerberos implimentations, but not yet supported by Windows Server. Can those be added to Windows Server? Also can you please think about adding sha-3 based ones too?Cache drive reconfiguration in Server 2025 Storage Spaces Direct cluster
We have a three node S2D cluster running Server 2025, with the storage in a 3 way mirror, running Hyper-V VMs. Each node has 4 x NVMe drives that are currently being used as cache drives, but which are connected to a RAID controller (in HBA mode), so in the S2D configuration they appear as SSD drives rather than NVMe drives. We've purchased the required cables and drive bays to be able to reconfigure the NVMe drives so that they're attached directly to the PCIe bus, so they'll show up as NVMe drives and hopefully give us a performance boost, so I'm just trying to plan the reconfiguration. I was hoping it would be a relatively simple process of shutting everything down, reconfiguring the storage and bringing everything back online, but ChatGPT suggests things won't be that easy and that a complete reconfiguration of the storage would be required. So in a nutshell, can the cache drives be reconfigured without a complete rebuild of the S2D storage ? Cheers, Rob
Securing ldap in WIndows AD
Hello everyone. I would like to secure the use of LDAP within an Active Directory domain. My domain has three Windows 2022 DCs. Searching online, I found these suggestions: Enforce LDAPS (LDAP over SSL/TLS) Disable Plain-text LDAP Bindings Block or Restrict Port 389 (Optional but Recommended) Enable Channel Binding Tokens (CBT) Does it make sense to only allow certain users to browse LDAP? Could limiting LDAP browsing to certain users cause problems? Thanks
NUMA Problems after In-Place Upgrade 2022 to 2025
We have updated several Hyper-V hosts with AMD Milan processors from Windows 2022 to Windows 2025 using the in-place update method. We are encountering an issue where, after starting about half of the virtual machines, the remaining ones fail to start due to a resource shortage error. The host's RAM is about 70% free. We can only get them to start by enabling the "Allow Spanning" configuration, but this reduces performance, and with so many free resources, this shouldn't be happening. Has anyone else experienced something similar? What has changed in 2025 to cause this issue? The error is: Virtual machine 'R*****2' cannot be started on this server. The virtual machine NUMA topology requirements cannot be satisfied by the server NUMA topology. Try to use the server NUMA topology, or enable NUMA spanning. (Virtual machine ID CA*****3-ED0E-4***4-A****C-E01F*********C4).

Windows 11 automatically restarting after install security Update — With GPO and WSUS.
Hi everyone, I’m facing a strange behavior with Windows 11 devices that receive updates through WSUS and are fully managed via Group Policy. Here’s the scenario: We have a GPO configured as follows: -Configure Automatic Updates → 4 (Auto download and schedule the install) -Scheduled installation every day at 10:00 -Install during automatic maintenance → disabled -Active Hours configured -Turn off auto-restart for updates during active hours → Enabled -Update deadlines set to 0 (to avoid any forced restart) -No other restart-related policies set in the domain Even with this configuration, after updates are installed, Windows 11 shows the following message: “Your organization manages update settings. We will restart and install this update at X minutes.” And then the device automatically restarts, even when: -a user is logged in -it is outside Active Hours -deadlines are disabled -no-auto-restart is enabled This behavior does not happen on Windows 10 — only on Windows 11.
SystemSettings. exe on Windows server 2025 crashes after installing Xbox game
I installed the Microsoft App Store on Windows Server and installed Minecraft. However, entering the system>display>graphics tab in the settings will cause the settings to crash.I tested both Bedrock and Java and found this issue. I think any Xbox game in the Microsoft Store should be able to reproduce this issue. + System - Provider [ Name] Application Error [ Guid] {a0e9b465-b939-57d7-b27d-95d8e925ff57} EventID 1000 Version 0 Level 2 Task 100 Opcode 0 Keywords 0x8000000000000000 - TimeCreated [ SystemTime] 2025-12-04T08:55:23.2042032Z EventRecordID 27146 Correlation - Execution [ ProcessID] 10988 [ ThreadID] 20000 Channel Application Computer WIN-JSD290TH0EL - Security [ UserID] S-1-5-21-868965638-952098041-1598110278-1002 - EventData AppName SystemSettings.exe AppVersion 10.0.26100.7019 AppTimeStamp f88449de ModuleName Windows.Gaming.Preview.dll ModuleVersion 10.0.26100.7019 ModuleTimeStamp 8e7f4dfa ExceptionCode c0000005 FaultingOffset 000000000003aadd ProcessId 0x1230 ProcessCreationTime 0x1dc64fbb631455a AppPath C:\Windows\ImmersiveControlPanel\SystemSettings.exe ModulePath C:\Windows\System32\Windows.Gaming.Preview.dll IntegratorReportId f2340132-82be-40d6-9c76-ec8fcbb9d19e PackageFullName windows.immersivecontrolpanel_10.0.8.1000_neutral_neutral_cw5n1h2txyewy PackageRelativeAppId microsoft.windows.immersivecontrolpanelAllow VMs attached to internal switch on hyper-V win2k19 access Internet
Hi, I have 4 VMs attached to an internal switch with IPs 10.10.0.*, assigned 10.10.0.1 to the switch. One of the NICs on the host has the 192.168.1.70 which I shared its connection with the internal switch but I am not able to browse internet from the VMs. What can be missing? Thanks
