Microsoft’s Firewall Fiasco: Windows Server 2025’s Unwanted Reboot Drama
Microsoft warns that some Windows Server 2025 domain controllers might become inaccessible after a restart, leading to app and service failures. The culprit? Servers loading the wrong firewall profile. The workaround involves restarting the network adapter—manually or via scheduled task—every reboot. A permanent fix is in the works.

Hot Take:
Oh, Microsoft! Just when you thought Windows Server 2025 would be the crown jewel of your server lineup, it turns out it might be more of a wonky tiara. Between reboot-induced firewall hiccups and the need for a network adapter CPR, it seems like Windows Server 2025 is setting the stage for IT admins to become full-time jugglers. Just make sure you keep your PowerShell wand handy to keep those domain controllers in line!
