Server 2025 Core ADDS DC, Network Profile Showing as "Public" and not as "DomainAuthenticated"
OS: Windows Server 20225 Standard Core (no GUI), build 26085.1 Role: ADDS, DNS ForestMode: Windows2025Forest DomainMode: Windows2025Domain Platform: Hyper-V guest When standing up a clean Windows Server 2025 using server core and configuring it as a domain controller, the network category (profile) always shows as "public." A clean load of Windows Server 2022 with server core as a domain controller has the same behavior. However, in Server 2022, the fix is to add DNS as a required service to the nlasvc (Network Location Awareness) service. Once that is done, the network category reflects "DomainAuthenticed" and persists between reboots. In Server 2025, the nlasvc service does not have the same requiredservices as Windows Server 2022, and it does not start automatically. Even after configuring the nlasvc service the same way it is in Server 2022 and adding DNS as a required service, the network category still reflects "public." The only way to get the network category to properly reflect the "DomainAuthenticated" status is to disable and reenable the network adapter after each reboot.Announcing Windows Server 2019 Preview Build 17623
Hello Windows Insiders! Today we are pleased to release the first build of the Windows Server 2019, our next Long-Term Servicing Channel (LTSC) release that contains both the Desktop Experience as well as Server Core in all 18 server languages, as well as the first build of the next Windows Server Semi-Annual Channel release. What’s New in Windows Server 2019 Build 17623 For every preview release, we will provide a focus area that we would like you to take a look at and provide us with feedback on. We encourage you to try out any functionality in the release and we welcome your feedback. Validation for every preview: There are two major areas that we would like you to try out in each preview release and report back any issues: In-place OS Upgrade (from Windows Server 2012 R2, Windows Server 2016) Application compatibility – please let us know if any server roles or applications stops working or fails to function as it used to Extending your Clusters with Cluster Sets “Cluster Sets” is the new cloud scale-out technology in this Preview release that increases cluster node count in a single SDDC (Software-Defined Data Center) cloud by orders of magnitude. A Cluster Set is a loosely-coupled grouping of multiple Failover Clusters: compute, storage or hyper-converged. Cluster Sets technology enables virtual machine fluidity across member clusters within a Cluster Set and a unified storage namespace across the "set" in support of virtual machine fluidity. While preserving existing Failover Cluster management experiences on member clusters, a Cluster Set instance additionally offers key use cases around lifecycle management of a Cluster Set at the aggregate. Windows Defender Advanced Threat Protection We provide deep platform sensors and response actions, providing visibility to memory and kernel level attacker activities and abilities to take actions on compromised machines in response to incidents such as remote collection of additional forensic data, remediating malicious files, terminating malicious processes etc. If you’re already using Windows Defender Advanced Threat Protection (ATP), preview these features by simply installing the latest preview build of Windows Server, and onboard it to Windows Defender ATP. Otherwise, sign up for the Windows Defender ATP trial on Windows Defender Advanced Threat Protection. Windows Defender ATP Exploit Guard Windows Defender ATP Exploit Guard is a new set of host intrusion prevention capabilities. The four components of Windows Defender Exploit Guard are designed to lock down the device against a wide variety of attack vectors and block behaviors commonly used in malware attacks, while enabling enterprises to balance their security risk and productivity requirements. Attack Surface Reduction (ASR): A set of controls that enterprises can enable to prevent malware from getting on the machine by blocking suspicious malicious files (e.g.: Office docs), scripts, lateral movement, ransomware behavior, and email-based threats Network protection: Protects the endpoint against web-based threats by blocking any outbound process on the device to untrusted hosts/IP through Windows Defender SmartScreen Controlled folder access: Protects sensitive data from ransomware by blocking untrusted processes from accessing your protected folders Exploit protection: A set of vulnerability exploit mitigations (replacing EMET) that can be easily configured to protect your system and applications To deploy a default set of Exploit Guard policy on Windows Server, you can run the following cmdlets: Set-MpPreference -EnableControlledFolderAccess Enabled Set-MpPreference -EnableNetworkProtection Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids 75668C1F-73B5-4CF0-BB93-3ECF5CB7CC84 -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids 3B576869-A4EC-4529-8536-B80A7769E899 -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids D4F940AB-401B-4EfC-AADC-AD5F3C50688A -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids D3E037E1-3EB8-44C8-A917-57927947596D -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids 5BEB7EFE-FD9A-4556-801D-275E5FFC04CC -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids BE9BA2D9-53EA-4CDC-84E5-9B1EEEE46550 -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids 92E97FA1-2EDF-4476-BDD6-9DD0B4DDDC7B -AttackSurfaceReductionRules_Actions Enabled Add-MpPreference -AttackSurfaceReductionRules_Ids D1E49AAC-8F56-4280-B9BA-993A6D77406C -AttackSurfaceReductionRules_Actions Disabled Add-MpPreference -AttackSurfaceReductionRules_Ids 01443614-cd74-433a-b99e-2ecdc07bfc25 -AttackSurfaceReductionRules_Actions Enabled $url = 'https://demo.wd.microsoft.com/Content/ProcessMitigation.xml' Invoke-WebRequest $url -OutFile ProcessMitigation.xml Write-Host "Enabling Exploit Protection" Set-ProcessMitigation -PolicyFilePath ProcessMitigation.xml Windows Defender Application Control Windows Defender Application Control—also known as Code Integrity (CI) policy—was released in Windows Server 2016. Customer feedback has suggested that it is a great concept, but hard to deploy. To address this, we are building default CI policies, which will allow all Windows in-box files and Microsoft applications, such as SQL Server, and block known executables that can bypass CI. The package contains an audit version and an enforced version. If the server doesn’t require additional drivers/applications, you can deploy the enforced version. Otherwise, you can use the audit policy, check uncovered executables, and then merge them into the default CI policy. To deploy the default code integrity policy, run the following commands: Copy-Item C:\CI\ServerDefault-EnforcedCI.bin C:\Windows\System32\CodeIntegrity\SiPolicy.p7b Reboot the server to allow code integrity service to load the policy. Failover Cluster removing use of NTLM authentication Windows Server Failover Clusters no longer use NTLM authentication by exclusively using Kerberos and certificate based authentication. There are no changes required by the user, or deployment tools, to take advantage of this security enhancement. It also allows failover clusters to be deployed in environments where NTLM has been disabled. Shielded virtual machines: Offline mode, VMConnect and Shielded Linux support You can now run shielded virtual machines on machines with intermittent connectivity to the Host Guardian Service by leveraging the new fallback HGS and offline mode features. Fallback HGS allows you to configure a second set of URLs for Hyper-V to try if it can’t reach your primary HGS server. To see how this can be used in a branch-office scenario, see Improved branch office support for shielded VMs in Windows Server, version 1709 on our blog. Offline mode allows you to continue to start up your shielded VMs, even if HGS can’t be reached, as long as the VM has started successfully once, and the host’s security configuration has not changed. (To enable offline mode, run the following command on the Host Guardian Service: Set-HgsKeyProtectionConfiguration –AllowKeyMaterialCaching.) We’ve also made it easier to troubleshoot your shielded virtual machines by enabling support for VMConnect Enhanced Session Mode and PowerShell Direct. These tools are particularly useful if you’ve lost network connectivity to your VM and need to update its configuration to restore access. These features do not need to be configured, and they will automatically become available when a shielded VM is placed on a Hyper-V host running build 17040 or later. For customers who run mixed-OS environments, we now support running Ubuntu, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server inside shielded virtual machines. Try it out—Create a Linux shielded VM template disk—and send us your feedback in the Feedback Hub. Encrypted Network in SDN Network traffic going out from a VM host can be snooped on and/or manipulated by anyone with access to the physical fabric. While shielded VMs protect VM data from theft and manipulation, similar protection is required for network traffic to and from a VM. While the tenant can setup protection such as IPSEC, this is difficult due to configuration complexity and heterogeneous environments. Encrypted Networks is a feature which provides simple to configure DTLS-based encryption using the Network Controller to manage the end-to-end encryption and protect data as it travels through the wires and network devices between the hosts It is configured by the Administrator on a per-subnet basis. This enables the VM to VM traffic within the VM subnet to be automatically encrypted as it leaves the host and prevents snooping and manipulation of traffic on the wire. This is done without requiring any configuration changes in the VMs themselves. Try it out—Configure Encryption for a Virtual Subnet—and send us your feedback in the Feedback Hub. Software Defined Datacenter If you are using Storage Spaces Direct, take a look at performance history for Storage Spaces Direct. Performance history for Storage Spaces Direct Administrators of Storage Spaces Direct can now get easy access to historical performance and capacity data from their cluster. Did CPU usage spike last night? When did this drive become slow? Which virtual machine used the most memory last month? Is network activity trending up or down? The cluster is pushing 1,000,000 IOPS – is that my new record? Previously, you’d need external tooling to answer these questions. No more! Previously, you’d need external tooling to answer these questions. No more! Beautiful new charts in Project Honolulu (and new PowerShell cmdlets, for those so inclined) empower you to answer these questions. There’s nothing to install, configure, or start – it’s built-in and always-on. Learn more at https://aka.ms/clusterperformancehistory.

Known issues In‑place OS upgrade: Domain Controllers. During an in-place OS upgrade, Active Directory (AD) Domain Controllers (DC) might not be upgraded correctly. So, back up any AD DCs before performing an in-place OS upgrade. Editing or creating policies for AppLocker can cause the MMC snap-in to crash when generated rules for a packaged app. After upgrading the operating system, the AppX database may have corrupted entries, which causes problems for components that use those entries. Testing of the Windows core may fail because of a timeout while attempting to load the test libraries Terms of Use All pre-release software made available to you via the Windows Server Insider program are governed by the Insider Terms of Use, which takes precedence over any license agreement that may be in the product.Windows Server 2022 adds support for Microsoft 365 Apps
