Turning Off Tamper Protection on Workstations
How do I turn off Tamper Protection on a domain-joined Windows 11 workstation? The problem is a workstation has Windows Defender in Passive Mode instead of being in Not Running mode after installing a 3rd party antivirus. Windows Defender is making running network applications from the servers much slower because it's still real-time scanning. I also suspect Tamper Protection is also preventing network drive exclusions from working on this workstation and on the ones that use Windows Defender without a 3rd party antivirus. I've tried adding every registry entry, Group Policy, and PowerShell command on the local workstation I could find to disable Windows Defender, but nothing works. I'm assuming this is due to Tamper Protection ignoring everything? This is an on-premises domain and doesn't use Microsoft Intune or Microsoft Endpoint Configuration Manager.22Views0likes0CommentsAOVPN / 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.

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, Rob68Views0likes2CommentsUnable to use a certificate from my Windows CA

Windows Admin Center version 2410, build 2.4.2.1. We're encountering an issue following the instructions outlined https://learn.microsoft.com/en-us/windows-server/manage/windows-admin-center/configure/update-certificate?tabs=powershell when replacing the WAC certificate. We've installed a certificate from a third-party CA in the local machine store. The common name matches the DNS FQDN and hostname of the server. Despite specifying the thumbprint of the 3rd party CA cert with the "Set-WACCertificateSubjectName" cmdlet, WAC binds to a different certificate issued by our internal CA for WinRM. The WinRM cert shares the same common name, but it has a later expiration date. I suspect WAC is picking the certificate with the latest expiration date. This also happens when using the GUI, even when we specify the 3rd party cert during customization. We've confirmed that the NETWORK SERVICE account has rights to the private key on the cert as well. I tried deleting the binding using netsh and rebinding to the updated thumbprint. While this is successful, and the output from "netsh http show sslcert" shows the 3rd party CA cert on the port 443 binding, the browser still presents the Internal-CA cert on 443 even after restarting the WinRM and Windows Admin Center services (and rebooting). It seems like there is an issue when multiple valid certificates exist with the same common name in the machine store. Additionally, the "Set-WACCertificateAcl" seems to fail in this case. The Configuration log contains the error below whenever it is run. Set-WACCertificateAcl: Unable to find machine key path for certificate. Skipping setting access control list. We'd prefer to use the 3rd party cert for the HTTPS port and the internal CA cert for WinRM. Is this possible?Solved99Views0likes1CommentWindows 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 11.405Views0likes1CommentWindows Admin Center Preview - 2511 English [MSI Corrupt]

I noticed yesterday that a certutil command I thought I could always rely on no longer works in Server 2025: >certutil -cainfo xchg CertUtil: -CAInfo command FAILED: 0x80070057 (WIN32: 87 ERROR_INVALID_PARAMETER) CertUtil: The parameter is incorrect. Executing certutil -cainfo xchg was a handy command which would ask the local certificate authority to output it's current CA Exchange certificate in Base64 format. If the CA didn't have a valid exchange cert at the time, it would immediately create a new one. Think of a CA Exchange certificate as a short-lived TLS cert which the CA provides clients when they need to upload private key material for archival. Anyway, looking at the help for certutil, the command still exists, however, it requires a new parameter: xchg [Index] -- CA exchange cert So, I figured [Index] had to refer to the CA certificate index. When you initially deploy an ADCS certification authority, the CA's initial certificate is at index 0. When you renew/re-key the CA, the new CA cert is at index 1. I tried using 0 for the [Index] parameter. No dice: >certutil -cainfo xchg 0 CertUtil: -CAInfo command FAILED: 0x80070057 (WIN32: 87 ERROR_INVALID_PARAMETER) CertUtil: The parameter is incorrect. I can't think of what else that parameter would be. Has anyone been able to successfully used this command on WS2025? If so, please share how!42Views0likes0CommentsQuestion About MAK Windows Activation

We have a DC, running Server 2016 to decommission (call it old server). One of the roles it had was Volume Activation (VA). This is Active Directory based and the keys AD holds are both for clients (Win11) and servers (2016/19/22/25). I have removed the VA role from the server and tested with a server which I added to the domain and the OS activated successfully, so it looks like it is working. I noticed the _vlmcs SRV DNS record was not deleted and is still pointing to the old server. Since the old server is no longer having the VA role, is it safe to delete the DNS record for the _vlmcs SRV record? What else do I need to take into account?

The update to LAPS for Windows 11 24H2 and Windows Server 2025 introduced new configuration options including the ability to use passphrases rather than passwords. Operationally this is add some benefits. However, the official documentation - https://learn.microsoft.com/en-us/windows-server/identity/laps/laps-concepts-passwords-passphrases#passphrase-word-lists doesn't provide a very good explanation for the setting "Short words with unique prefixes" The examples in the documentation and observations from implementation do not align with the short description. For example, from implementation: IodineIslandNectarRagweedCivilianZillion The word phrases are not exactly short; 6+6+6+7+8+7 = 40 characters, and nor is their a unique prefix. Does anyone have a better explanation as to the meaning of passwordcomplexity setting 8 in LAPS (post 24H2)? Cheers Paul P.S. the LAPS password above is no longer valid as it has been rotated.48Views0likes0Comments
