I've been running into issues trying to connect to a handful of our Windows servers (2022, 2019, and 2016) via RDP. It's throwing up a message that says, 'This computer can't connect to the remote computer. Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator.' The specific error code is 0x904, with an extended error code of 0x7 and a timestamp of 04/24/25 at 2:28 PM UTC. This seems to happen on about ten servers, and the issue started around a month ago. All admins are facing this issue regardless of their location, whether they're on the local network or VPN. I read that error code 0x904 typically points to network connection problems, but servers on the same subnet work perfectly fine. Has anyone experienced this before?

I have the same issue as you. I've tried connecting from both LAN and VPN, and I can stay connected for a short while before getting the same error. I wonder if it links back to a recent Windows Update that caused similar problems last month. Could be worth looking into!
This might be a firewall issue. Have you tried temporarily disabling the firewall on one of the affected servers? Also, it’d be good to check if you experience the same problem using the Microsoft Remote Desktop app from the Microsoft Store. Sometimes these things can be app-specific.
I've seen this error pop up for some users, all remote so far. I couldn't replicate it from my setup, which is on a different remote system, using the same VPN. But since you're experiencing it even on local subnet, I’m starting to think it might be a client issue. I had a user come in recently, and after swapping out their laptop, my account worked fine, but theirs still showed the same error. Turns out, their user profile was corrupted. Rebuilding it solved their problem, so that could be worth investigating for you.
