Windows 10 Pro Laptop, Version 1909, OS build 1863.959 attempting to connect via RDP to Windows Server 2019 Standard (Hyper-V VM), Version 1809, OS build 17763.1282.
Observations: 1) Remote connection is allowed. 2) Remote session, once connected, will freeze almost immediately and becomes unresponsive to ALL input (mouse, keyboard, etc.). 3) Remote session must be disconnected forcibly. 4) Connection attempts to the PHYSICAL server, also running Windows Server 2019, works fine. 5) Likely unrelated but worth noting, the 2019 server hosting the RDS session host deployment has started randomly stopping the Remote Desktop Connection Broker service which has to be manually restarted. I am supporting a 100% remote workforce due to COVID-19 and this has to work! Any help appreciated.
