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.

The Windows Performance Monitor is one of the best built-in tools you’re not using

Performance Monitor is an advanced tool in Windows 11 that provides detailed insights into system performance, allowing users to monitor resource usage in real-time. It offers various performance counters, including battery status and network adapter performance, and supports different visualization formats like line graphs and histograms. Users can display multiple graphs simultaneously and save specific settings as an HTML file for easier analysis. Additionally, Performance Monitor can generate detailed reports based on predefined Data Collector Sets, enabling tailored data collection for critical metrics such as CPU usage and processor interrupts. Users can access Performance Monitor via the Start menu or by typing "perfmon" in the Run dialog.

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.

Windows Server 2025 Restart Bug Breaks Connection with Active Directory Domain Controller

Microsoft has warned IT administrators about a significant issue affecting Windows Server 2025 domain controllers, which may struggle to manage network traffic after a system restart. This problem arises because the domain controllers revert to the standard firewall profile instead of the required domain firewall profile, leading to potential inaccessibility on the domain network, application failures, and open ports that could pose security risks. The issue specifically affects Windows Server 2025 systems with the Active Directory Domain Services role, while client systems and earlier server versions remain unaffected. To address this, Microsoft recommends a temporary workaround: manually restarting the network adapter using PowerShell with the command Restart-NetAdapter * after each reboot. Administrators are advised to create a scheduled task for automation, monitor domain controllers for disruptions, and minimize unnecessary restarts. Microsoft is working on a permanent fix, with an update expected in the future.

Microsoft: Windows Server 2025 restarts break connectivity on some DCs

Microsoft has warned IT administrators about a potential issue with Windows Server 2025 domain controllers (DCs) becoming inaccessible after a restart, due to defaulting to the standard firewall profile instead of domain-specific settings. This mismanagement can lead to DCs being unreachable on the domain network or improperly accessible through restricted ports and protocols. A workaround involves manually restarting the network adapter on affected servers after each reboot, and Microsoft recommends setting up a scheduled task for this. The company is working on a permanent solution for a future update. Additionally, Microsoft has alerted users to another issue with Windows Hello logins related to the KB5055523 April 2025 security update and has implemented a fix for authentication issues with Credential Guard and the Kerberos PKINIT pre-auth security protocol.

How to Fix the “Windows Could Not Find a Driver for Your Network Adapter” Error

The "Windows Could Not Find a Driver for Your Network Adapter" error occurs when Windows cannot communicate with the network adapter due to outdated, corrupted, or missing drivers. To resolve this issue, users can reinstall network adapter drivers by opening "Device Manager," locating the network adapter under "Network Adapters," right-clicking it to select "Uninstall Device," confirming the uninstallation, and then scanning for hardware changes to prompt Windows to reinstall the adapter and its drivers. Alternatively, users can perform a network reset, which removes all network adapters and restores settings to their original defaults. This involves opening the Settings app, selecting "Network & Internet," clicking on "Network reset," and then clicking "Reset now" to initiate the process.
