IP Address Management (IPAM) in Windows Server automates and centralizes the management of IP address infrastructure, allowing administrators to monitor, manage, and audit DHCP and DNS servers. Setting up IPAM involves several steps: verifying prerequisites (supported Windows Server version, active directory domain, and operational DHCP/DNS roles), installing IPAM through Server Manager or command prompt, configuring IPAM for file sharing and access settings, configuring server discovery, and managing servers and settings. To add an IP address to IPAM, users access the IPAM console, navigate to the IP Address Space section, select the desired IP Address block, and provide necessary details before saving the changes.

Microsoft has addressed an issue affecting the launch of certain applications on Windows 10 22H2 systems for non-administrative users, which arose after the September 2024 preview cumulative update (KB5043131). The problem involved child processes of applications running at low Integrity levels instead of the required medium levels, impacting applications like Quick Assist, Microsoft Teams, and Windows Narrator. This issue occurs when applications with UIAccess=true attempt to run under non-admin accounts. Affected applications are typically launched from secure directories, including ProgramFiles, %systemroot%system32, and %systemroot%syswow64. Microsoft is rolling out a Known Issue Rollback (KIR) to resolve the problem, which will automatically propagate to home and non-managed enterprise devices within 24 hours. For enterprise-managed devices, administrators must apply the KIR Group Policy via the Group Policy Editor and restart affected devices. Microsoft has previously used KIR to address issues on Windows Server 2019 and Windows 11 systems.

A cyberattack exploited a vulnerable web server targeting public-facing applications using a web shell that allowed execution of PowerShell code and file transfers. Attackers deployed the remote management tool ngrok to navigate laterally within the network, focusing on the Domain Controller by exploiting the CVE-2024-30088 vulnerability, a Windows Kernel Elevation of Privilege flaw. They used an exploit binary introduced through the open-source RunPE-In-Memory tool to escalate their privileges.

Microsoft has released build 26304 of Windows Server for the Windows Server Insider Program, transitioning to the Windows Server 2025 branding. The key feature introduced is Windows Defender Application Control for Business (WDAC), which enforces a strict list of approved software and includes a predefined default policy for implementation via PowerShell cmdlets. The Windows Server 2025 Security Baseline Preview is also available, featuring over 350 preconfigured settings based on Microsoft’s best practices, categorized by server roles such as Domain Controller, Member Server, and Workgroup Member. Users are advised to preview the security baseline only on test systems due to potential irreversible configurations. The new build will be automatically delivered to Server Flighting participants, and the updated Feedback Hub app is available for Server Desktop users. Known issues include mislabeling in flight references, PowerShell script malfunctions in WinPE, intermittent upgrade failures from previous Windows Server versions, potential crashes when archiving event logs, and restrictions for those with Secure Launch/DRTM code path enabled.

Microsoft has addressed issues caused by the Windows KB5043145 preview update, which led to reboot loops, system freezes, and failures in USB and Bluetooth device connectivity. Users reported their systems either loading the Automatic Repair tool or entering BitLocker recovery mode after repeated reboots. The update caused hardware connected via USB and Bluetooth, such as keyboards and printers, to malfunction, indicated by a yellow exclamation mark under the USB Host Controller in Device Manager. To resolve these issues, Microsoft implemented a Known Issue Rollback (KIR) to reverse the problematic update and is working on integrating this fix into an upcoming Windows update. Administrators managing affected Windows enterprise devices can resolve the issue by installing the Windows 11 22H2 KB5043145 240904_041021 KIR Group Policy, which requires a system restart to apply. Microsoft has previously addressed similar issues with updates affecting Windows Server 2019 and other versions.

Microsoft is positioning itself to attract VMware customers following VMware's acquisition by Broadcom. The upcoming release of Windows Server 2025 will include enhanced features for Hyper-V, such as revised GPU partitioning, dynamic compatibility for live migrations between hosts with different CPU architectures, improved virtualization-based security, and simplified deployment for smaller organizations. Broadcom's history of selling off underperforming products raises concerns about VMware's stability, prompting customers to reconsider their options. Microsoft is offering solutions like the Azure VMware Solution and the VMware Rapid Migration program to facilitate transitions away from VMware. The enhancements in Windows Server 2025 aim to address enterprise needs and may encourage users to switch from VMware.
