Microsoft fixes unreachable Windows Server domain controllers

Microsoft addressed a significant issue with Windows Server 2025 domain controllers that made some servers unreachable after a restart, affecting applications and services reliant on them. The problem was due to servers loading the standard firewall profile instead of the intended domain firewall profile after a reboot, leading to improper network traffic management. This misconfiguration caused accessibility challenges for services and applications on affected servers. Microsoft released the KB5060842 security update to resolve this issue during the June 2025 Patch Tuesday. A temporary workaround involves manually restarting the network adapter on affected servers using the Restart-NetAdapter * PowerShell command, which must be done after each reboot until the update is installed. Additionally, Microsoft fixed another issue preventing some users from logging into accounts via Windows Hello after the installation of the KB5055523 April 2025 security update.

Why I Use simplewall Instead of Windows Firewall (And You Should Too)

Simplewall is a rule-based firewall controller for Windows that enhances the Windows Filtering Platform (WFP) without replacing it. It allows users to manage network access for applications and services with a user-friendly interface, supporting advanced features like filtering rules by IP, port, or protocol. Users can create tailored profiles for different scenarios and have comprehensive control over network interactions, including blocking telemetry data and automatic updates. Simplewall is lightweight, portable, and operates without background processes or telemetry, ensuring a straightforward user experience. Setting up simplewall involves downloading it, extracting the files, and enabling filters, allowing users to establish a functional firewall profile quickly. While it offers many advantages, such as being open-source and compatible with older Windows versions, it may be overwhelming for beginners and lacks detailed app profiling compared to premium firewalls.

Windows Server 2025 may lose DC connectivity after restart

Microsoft has warned about potential accessibility issues with Windows Server 2025 domain controllers after a restart, where affected servers revert to the default firewall profile, disrupting applications and services. A temporary workaround involves manually restarting the network adapter on the impacted servers using the PowerShell command: Restart-NetAdapter *. This workaround needs to be reapplied after each restart of the domain controller, and Microsoft recommends setting up a scheduled task to automate this process. Windows Server 2025, launched earlier this year, introduced new features and security enhancements but has faced previous issues, including freezing Remote Desktop sessions and accidental upgrades from Windows Server 2022. Developers are currently working on a permanent solution for the domain controller issue.
