After applying the March 2021 updates to my Windows 10 20H2 home computer, I am unable to reconnect to my office computer which is also running Windows 10 20H2 and also received the March 2021 updates. I get the Remote Desktop Error "You have been disconnected because another connection was made to the remote computer"
This problem started yesterday morning. I generally connect to my office computer in the morning and disconnect in the evening. This has been working flawlessly for a year now. The problem only just started.
Yesterday, I found that I could reconnect sometime in the afternoon. I completed some work and disconnected again in the evening. This morning, when I tried to reconnect, I got the same error. Based on the message, it seems like part of the session is being held until it times out. I will see if I can reconnect again this afternoon.
My office PC is an AD Domain participant. My home PC is not. I typically use the Remote Desktop MS Store App to connect, which is up to date. However, I also tried connecting with the built-in Remote Desktop application and could not connect either.
I rebooted my home PC before attempting to reconnect. I also rebooted my remote PC yesterday, after I was able to reconnect in the afternoon. (I reconnected, rebooted, and reconnected again. Later that evening, I disconnected. This morning, I could not reconnect.)
