Actually I’m going to repy to myself here, I think I have proof SMB1 is not required, bear with me…
My ROCK install is running on a NUC 8i3
My Roon Remote is running Windows 10 22H2. Windows is configured thus;
SMB1 not installed:
Insecure Guest Authentication disabled:
And with this configuration I CANNOT connect to \\ROCK\DATA as expected:
However, if i just change the insecure guest authentication registry key to 1:
Now I CAN access \\ROCK\DATA from Windows 10 with no SMB1 installed:
Id be interested if anyone else has the same result!
