There is a well known and persistent issue with Windows 10 terminal aka Remote Desktop client. The client software runs, allows you to initiate a connection, but either fails to connect or drops the connection – sometimes right away or shortly after.
After many attempts to fix this using suggestions from various sources on the internet – turning off smart card and/or printers option for the connection, etcetera – none of these resolves the problem across the board for all users.
There is a very simple free, and in my opinion, FAR more versatile and robust alternative client available.
