Problem mapping individual Shared Folder as network drive

[Kosymodo]

Hey folks

I have a question which hopefully will be quick to resolve...

I have successfully used WebDAV to map my (entire) NAS as a network drive on my laptop. However, whilst this works fine, I'd like to refine this to mapping only a single Shared Folder (Documents) as the network drive. The problem being that if I append either \Documents or /Documents or \Documents\ or /Documents/ to the folder path which works for the entire NAS, it won't map, it just continually asks me for my credentials.

What am I doing wrong? I feel it's almost too obvious for me to see
