Static IP Issue with Windows Server 2022
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.
WAC vMode fails validating SMB
Hi Reviewing vMode and try add a Hyper-V 2025 (non hyperconverged) cluster with a FC SAN. Fails on Validating "SMB port accessibility". Have gone through firewall settings and opened all neccesary ports that i can find mentioned. Even tried without FW turned off without any success so hit the wall now. WAC vMode is installed on a vm running Win2025std and in same domain as the cluster (and hosts) i try to add. Probably some obvious thing i have missed so any suggestions?
Certificate Error Connecting to only to some of the Cluster's resources
Latest version of WAC, winrm configured to connect over HTTPS. No issues connecting to the servers that are members of the cluster, or clients and other servers in our AD. No issues connecting to the cluster Dashboard (I can see health, CPU usage, etc.) and some of the resources (such as Drives, Volumes, Servers). Configuration -> Settings or Security works fine. It's only when I go to some resources, such as virtual switches, GPU's or a handful of others that I get errors connecting to member servers; Specifically, the error will state that for each server: Connecting to remote server servername.local failed with the following error message : The server certificate on the destination computer (servername.local:5986) has the following errors: The SSL certificate contains a common name (CN) that does not match the hostname. The one oddity I see is that .local is being added to the end of the server name. Also, servername will not contain the domain extension, just the name. Here's what I've checked so far: DNS is correct for the member servers and the cluster, both with Host (A) and PTR entries, can be pinged and resolved. As far as I can tell the certificates are setup correctly, no issues connecting to the member servers individually, or the cluster at first. The AD entry for the cluster is in place with the correct permissions for the cluster's service account I've read that .local is appended if the server/cluster is not part of AD, but that's not the case. We have two additional clusters and this issue does not appear on them. I also have not been able to identify any obvious differences between the setup of the two fully functioning clusters and this one. In the Event Viewer on the WAC server, under Applications and Service Logs _> WindowsAdminCenter, I can see Error Entries ID 304 for each member server with a similar message as above: Unable to create PowerShell session on node, status: 400, error code:PSRemotingTransportException, error message:Connecting to remote server server.local failed with the following error message : The server certificate on the destination computer (server.local:5986) has the following errors: The SSL certificate contains a common name (CN) that does not match the hostname. For more information, see the about_Remote_Troubleshooting Help topic.. As a side note, opening a remote Powershell session to each member server via WAC works fine and by contrast, in the WAC Event viewer there will be corresponding Information entries list the server's FQDN. Here's an example Category: Microsoft.AspNetCore.Hosting.Diagnostics EventId: 2 SpanId: 50d2635d1f6eb737 TraceId: b8c8e1de80ac2f84f1230c5ec3305b38 ParentId: 3e0619ce2c5decca ConnectionId: 0HNMB39BE0AS7 RequestId: 0HNMB39BE0AS7:0000009F RequestPath: /api/PowerShell/nodes/serverFQDN/invokeCommand Request finished HTTP/2 POST https://WACserverFQDN:6601/api/PowerShell/nodes/serverFQDN/invokeCommand - 200 - application/json;+charset=utf-8 230.3283ms It seems that when it comes to accessing only some of the cluster's resources WAC no longer has the member servers FQDNs, and I'm not sure where to look for changing that. Anyway, any guidance would be appreciated.
Out of Band Cumulative Updates Question
I installed March 2026 Cumulative Update on a new server instead of April due to some RC4 changes to test something. I noticed that after the update installed in the event viewer it thinks the June 2026 update was installed. I don't see the June update under installed updates but shows up in update history. The build version of the server matches with the March 2026 update. Is this a weird side effect of installing a superceded update? I'm having trouble understanding what is going on.
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!
RDP Client - incorrect keyboard shortcut action in German localization
In the above dialog, when any of the checkbox controls has the focus, ALT+V toggles the state of the checkbox. ALT+V obviously should trigger "Verbinden" (Connect) instead. But not when the dialog first appears, i.e. none of the controls has the focus. Then ALT+V does nothing. As long as any chekbox control has the focus, ALT-V toggles its state. If the command button "Abbrechen" has the focus, ALT-V does nothing, i.e. ALT-V never triggers "Verbinden" except the command button "Verbinden" itself has the focus. Steps to reproduce: Start RDP client to connect to a remote machine Press ALT-Z -> "Zwischenablage" will be checked as expected Press ALT-Z again -> "Zwischenablage" will be unchecked as expected After any of the two steps above, press ALT-V -> "Zwischenablage" will be toggled instead of triggering "Verbinden" Same goes for "WebAuthn". Depending on the devices on the local machine an the RDP settings for sharing those, their might be more options with checkbox. I suspect those to behave similarly wrong when pressing ALT-V. The OS doesn't seem to make a difference. I see the same behavior on both Windows 11 and Windows Server 2022.

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 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.

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 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.

We have an AD-integrated DNS environment that has accumulated a large number of reverse lookup zones over time, created without any parent zone — essentially DNS sprawl from years of admins creating individual subnet zones rather than working from a parent. We currently have approximately 80+ reverse lookup zones including: Dozens of x.10.in-addr.arpa zones covering various 10.x.x.x subnets Multiple x.172.in-addr.arpa zones A handful of others including 100.192.10.in-addr.arpa, 168.192.in-addr.arpa, 204.167.in-addr.arpa, 215.204.167.in-addr.arpa, 135.7.in-addr.arpa None of these were ever delegated from a parent zone — they were just created independently. The 10.in-addr.arpa zone does not exist. Domain controllers are a mix of Windows Server 2019 Standard (majority) and Windows Server 2025 Standard. Our goal is to create 10.in-addr.arpa as the consolidation point going forward — new registrations go there, and we migrate existing child zones into it one at a time, deleting old ones as we go at a pace we're comfortable with. Before touching anything, we need to understand what creating 10.in-addr.arpa will actually do to the existing child zones. Specifically: Will existing records in the child zones be deleted? We've seen the TechNet article documenting records vanishing when creating a child zone under an existing parent — does the same destructive behaviour occur in the reverse direction? Will auto-delegations be created in the new parent zone pointing to the existing child zones, and if so how quickly? Will the child zones continue to function normally for queries while the parent exists alongside them? Will dynamic registration start hitting the parent zone for subnets not covered by an existing child zone, or will something unexpected happen? We can't test this in a lab as we don't have a replica environment available, and can't risk touching production without understanding the behaviour first. Pointers to any documentation covering this specific scenario would also be appreciated — we've been unable to find anything that addresses creating the parent after the children already exist independently.Enforcing LDAP Signing breaks ADDS Replication (repadmin.exe)
Hi All, After months of auditing Event ID 2889 and remediating application simple binds (clear text usernames/passwords over the wire), I was left with only SASL binds (that do not use signing). I proceeded to set LDAP signing to 'negotiate' as per the GPOs below, and several dozen Microsoft KBs and from the community e.g.. https://learn.microsoft.com/en-us/troubleshoot/windows-server/active-directory/enable-ldap-signing-in-windows-server Default Domain Controllers Policy Domain controller: LDAP server signing requirements: None: Data signing is not required in order to bind with the server. If the client requests data signing, the server supports it Default Domain Policy Network security: LDAP client signing requirements: Negotiate signing: If Transport Layer Security/Secure Sockets Layer (TLS\SSL) has not been started, the LDAP BIND request is initiated with the LDAP data signing option set in addition to the options specified by the caller. If TLS\SSL has been started, the LDAP BIND request is initiated with the options that are specified by the caller. I still noted 1,000s of Event ID 2889s (0 – SASL Bind that does not use signing), primarily from DCs, and ::1 addresses I proceeded with enforcing LDAP signing ("Require Signing" for both GPO settings above) and noted: LDAP authentication was occurring via Kerberos (SASL/SPNEGO) with simple binds blocked as per tracing (and ldp.exe) confirmations: Error <8>: ldap_simple_bind_s() failed: Strong Authentication Required Error 0x2028 A more secure authentication method is required for this server. However, I came to work the next day and performed a manual replication: Repadmin /Syncall /APeD LDAP error 8 (Strong Authentication Required) Win32 Err 5. So I had to revert back to Negotiate. How can customers enforce LDAP signing if common Microsoft ADDS executables like repadmin.exe still use Simple Binds? Any ideas appreciated, thank you in advance.
