Network share to Nucleus hard drive

So, I added an internal hard drive to my Nucleus. I have transferred my cd data to it via windows but for the life of me I cannot add the drive as a network share. I must have tried every configuration of smb and IP address following help here and still no joy.
What might i be doing wrong?

Browse to the IP address or NUCLEUS name in file explorer: \\NUCLEUS\Data\Storage\InternalStorage
