Greetings! We are in the process of replacing our traditional PC's with Lenovo Thin Client. I have created a test environment in Azure with Server 2019 DC Edition acting as AD and 1 VIrtual Machine for client to connect via RDP or RDWeb. RDWeb is working fine but after few minutes of activity the session crashes. Hence I tried MSTSC from a traditional desktop with Windows 10 pre-installed. RDP session stays active and performance compare to web session is far better. If I try to connect with FreeRDP or RDP from Lenovo Thin client which comes with default O/S LeTOS. Connection couldn't be established. It simply says ''Server is not reachable / invalid. Any suggestions would be helpful.
