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.
