Unraid - unable to access share after windows 10 h2 2020 upgrade

After upgrading to windows 10 h2 2020 I was no longer able to access my unraid server from my windows desktop. it looks like this is due to new security policy's within windows.

When I would try to access a share I would get the error "You Can't Access This Shared Folder Because Your Organization's Security Policies Block Unauthenticated Guest Access."

To allow access I found I just needed to change a registry key to allow insecure guest auth.

This key can be found by opening regedit from the start menu and going to this path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters

AllowInsecureGuestAuth change this from 0 to 1
