Hello. I had the same issue. Found out the root cause was that my work PC did not allow guest access to the share drive. Resolved by:
1) Open file explorer
2) Left click on 'Network'
3) Select 'Map network drive......'
4) Tick the 'Connect using different credentials'
5) Enter the address '\\IP address of the linkstation\share' into the folder box.
6) Click 'finish' and then enter your linkstaion login credentials to access the share drive.
Hope this helps!
