RDP - Windows 10 FAH Client Crash/Freeze/Stops Running

[bruce]

It blocks access to new assignments for the GPU.

...Probasbly because the Windows user who owns the GPU is not logged. Windows refuses to allow the GPU to function if you're the owner of the desktop a|ADN you are logged on. The GPU simply does not function in the bsckground.

[ajm]

IF you sign out, it closes everything, including here GPU-Z, HWMonitor, and of course FAH. Then if you go in local, you find the lock-screen and if you enter your pw, you find the machine just like after startup.

I understand that it may not be ideal for some use cases, but to say that RDP blocks access for the GPU is misleading, in my opinion. Because as a matter of facts, many if not most users of Windows folding rigs can use it without GPU issue whatsoever. And it's really convenient. To just advise against it wholesale is more a loss than a useful precaution.

[bruce]

If you're operating within your LAN, VNC (TightVNC) is great but since it's not secure over the Internet, TeamViewer is better for this case. On Linux, SSH is good.
None of them cause FAHClient to hang.

[gunnarre]

Yes, I'll probably use VNC over an SSH tunnel.

I think some who think Remote Desktop work fine have misunderstood what's happening here. If I disconnect the RDP connection then all applications including web browser, office, and FAHClient will keep running, and CPU folding continues, but when the GPU slot finishes with the current Work Unit, it will download but not start on the next one.

I'm using Microsoft's MacOS Remote Desktop client to connect to a Windows 10 Enterprise (Pro) machine.

Removed lines of the CPU slot folding away happily while I was sleeping, but the GPU slot being stuck before 0%. Then in the morning when I logged in to the machine via RDP:

When I got back to the machine I logged in to a local session, and have stayed off Remote Desktop on this machine - the GPU is folding normally since.
