I figured out that the only way to view the folders is to map the drive. So go on windows explorer right click on network and click on Map network drive. then insert \\ followed by the iP address of your NAS and press browse. It will open up all the folders you have on your nas.

Hello thanks for the reply - unfortunately mapping a network drive has the same result, i.e - I get the same error message because something is not quite right.

Stephen B - I think you may be right, it must be down to the credentials. Please could you confirm exactly which usernames/passwords need to be identical? Does a "user" named "admin" need to be created in the dashboard with the same password used for Windows logon? Following on from that, does my windows login username need to be ADMIN too? Are there any specific sharing protocols that I should turn off/turn on? Should I be creating anything in Windows Credentials Manager?

Apologies for the number of questions..

Thanks in advance
