LS200 Hidden Shared folders

[mitchellm203]

So I am using a Linkstation 200, and I am trying to create a shared folder to back all of my small business PCs up too. I have made the folder hidden so that no one can see it on the actual shared area. I have set my attributes that only admin has rights to view whats on it. when I map try to map to the folder via explorer it asks for credentials which i enter but says i do not have access. \\ip address\PCbackups    i am using windows 7 but cannot figure out why it is denying my access when i am using the admin account.
