I recently faced a nail-biting moment while working on a new Windows Server 2025 domain controller. While going through the local security policies, I noticed that the "Allow log on through Remote Desktop Services" policy was set to "Not Defined" instead of listing the usual admin groups. Curious, I opened the policy, saw it was empty, and naively clicked OK without changing anything. Little did I know, clicking OK on an undefined policy actually sets it to an empty state, meaning no one could log in via RDP anymore. After a panic-filled ten minutes, I remembered my manager's advice to install remote console access. Luckily, I was able to get back in locally, adjust the RDP policy, and save the day. This experience taught me a serious lesson: never click OK on a policy dialog unless you're ready to make changes! Has anyone else had a similar mishap?

For real! I always revert back to settings from a while ago just to avoid mistakes. 2019 was a simpler time, right? 😂
Absolutely! The golden rule is to hit Cancel on any dialog box if you're unsure about changes. You mentioned locking yourself out of the VM, but luckily, you had that remote console setup. Just a reminder: even in VMs, console access is like being right there with the physical machine! Just be careful next time and double-check before making changes.
This just proves that the old timers really do know their stuff! You'd think with all our experience, we'd remember to play it safe.
Totally agree! I always feel like diving into the sea after a reboot to ease the stress! Just kidding, but seriously, checking after changes is key.
Another good takeaway is to check your settings right after a reboot. Don't just assume everything will be fine. Always validate!
