My listening process is to rip or download music to a USB stick which is my ‘work in process’ location - just to make sure I give everything full attention on initial purchase before transferring the music (folders) to my NAS.
A week ago everything worked fine, I popped in the USB and dragged the files over to my networked NAS. Now following a Windows update to 1803 & 1903 versions I understand that ‘Homegroup’ has been abolished and when I try to drag the files over to the network I get the red circle with a bar through it so I can’t copy from the USB to the network anymore.
I take it your ‘network’ in regards to this is a mapped network drive?
I would goto network on the left see if it find your bad and delink to it if it does not show which is very likely then you need to determine its ip and in the address bar of network tab type \theipaddress and you should get to it that way then remap the drive
