Ok. So I got it Working without knowing what I did.
Had to set up the Win 10 Computer again and here I stand again with the same Problem.
The Windows 10 Machine does not seem to find the Filepath of the Mapped Drive on the Editing Machine.
I Mapp the NAS Drive to Davinci in Mac
/Volume/Projects_WIP (As a mapped Mount in Davinci Ill punch in Z:/ for the same Mapped NAS Drive in Win10)
On the Win10 Side
Z:/ as the mapped NAS drive and as a mapped Mount point in Davinci /Volume/Projects_WIP
Windows can read write and render to the Z:/ Drive and has Admin rights
Mac can Write to the /Volume/Projects_WIP and can render to it
If I start the remote render on Mac and the Win10 Machine loads the project all media turned up as offline.
The file path that Win10 shows the Media in is \Volume\Projects_WIP The Backslahes are the wrong way. What am I doing wrong here. If I change the Mapped drive in Davinci under Win10 to \Volume\Projects_WIP with the wrong Backslash nothing changes..
Thank you for anyone pointing me in the right direction
