If I reboot the Windows 10 box, or connect to it via another remote tool (eg TeamViewer) and then disconnect, I can reuse MRD to connect again.

I can connect initially, but if I suspend the Mac and reopen it and try to connect via MRD I get the error 'Your session ended because of an error. 10.2.1 (1143) Beta on Mac High Sierra 10.13.6 attempting to connect to a local (LAN) Windows 10 system.
