Spontaneous 0x80070035 The network path was not found

Hello!

I have two computers, both run Windows 10, One runs Pro and the other Home (odd considering both were free upgraded from 7 Pro, but that is a currently unanswered for 2 month question for Microsoft to resolve...). Onto business, my main PC (Triton hereon out) spontaneously throws the 0x80070035 (network path not found) error. The other PC (Prometheus) is always on, its always connected. To add insult to injury, there is nearly always an open VNC connection (Prometheus runs headless, no monitor, hence VNC), so I know the computer is connected at all times and it is at least visible in one way as the VNC connection never drops. This problem has been going on since I got the free 10 upgrade. Both previously used Windows 7 Pro and had no connection problems with each other.

So here is what I have tried so far.
- Enable NetBIOS over TCP/IP
- Restart both PCs
- Exit homegroups and make a new one
- Uninstall VirtualBox incase it was trying to use its (VirtualBox) imaginary network on both machines (both are now running it again though after it didn't work)
- Disabling / exiting VNC Viewer/Server on both servers before connecting

The only odd thing I have noticed is my router/modem in one has six IPv6 addresses for Prometheus, whilst Triton only has two. Both have one IPv4 assigned, see this image for info. If it matters, I connect to Prometheus via VNC by name 'Prometheus' instead of its local IP. Incase Windows does it a different way?
remember this is spontaneous, sometimes (i'd say about 30% of the time) it connects and I can view and copy/edit Prometheous' files no questions asked, the other times it will throw this error but after a few tries it will let me in.
