I recently upgraded my Windows Server from 2019 to 2022, but now I can't connect remotely via RDP (using mstsc). I keep getting an error message indicating problems with the Connection Broker validating my RDP file settings. The specifics are:
- **Error Code**: `0x3`
- **Extended Error Code**: `0x410`
The only way I've found to access the server is by using the command "mstsc /admin" which works without any issues. Our setup involves using a license host server for RDP, so we don't work with local files as the error suggests. I've already attempted uninstalling and reinstalling licenses and also removed the Remote Desktop Services roles, but nothing seems to resolve the issue. Any insights would be greatly appreciated! 🙂

It sounds like you might have licensing issues on your hands. Is your RD Session Host server's license server also upgraded to 2022, equipped with the appropriate 2022 RD CALs? That could be the culprit here!
It’s likely a licensing issue, for sure. In my experience, it’s better to redeploy the whole Remote Desktop Services (RDS) farm after a major OS upgrade like this instead of upgrading in place. Doing testing in an isolated environment might also save you some headaches later.
The reason why using the /admin switch works is that it bypasses the requirement for a CAL, which is probably why you're facing trouble with the regular access. Sounds like a licensing setup problem. You might want to review that!
Yes, we figured out the license host server needed the upgrade as well, but unfortunately, we are still encountering the same error even after doing that.
