ROCK on NUC - Network file sharing a security risk?

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!
