Microsoft: Windows Server 2025 restarts break connectivity on some DCs
Summary: Microsoft has notified IT administrators about a critical issue affecting Windows Server 2025 domain controllers, which may become inaccessible after a restart. This problem arises when the servers incorrectly load the standard firewall profile instead of the domain firewall profile, leading to potential failures in services and applications. A workaround involving manual network adapter restarts and scheduled tasks is recommended while a permanent fix is in development.

Affected: Windows Server 2025 domain controllers

Keypoints :

  • Domain controllers might not manage network traffic correctly after a restart.
  • This issue can cause applications and services to fail or become unreachable on the network.
  • A workaround includes manually restarting the network adapter using PowerShell; a scheduled task is recommended for automation after reboots.
  • A permanent fix is being developed and will be released in a future update.
