I work in a small office that has about 10 computers connected to a a "BUFFALO LinkStation 410 2 TB High Performance NAS Personal Cloud Storage and Media Server - LS410D0201." My boss wants to password protect some our files to limit access. So I tried to set this up for him. I can connect to the NAS set up user accounts and password without a problem and password protect the folder.
The problem is that only one computer cannot access the password protect folder mine. Any other computer on the network I try can. I have also moved the computer to other connections and it can access the folder. All our Ethernet cables are run through the walls so a permanent move is not possible. This issue only happens when a folder is password protected otherwise I can access all files and folders.
All the PC's in our office us Windows 7 except one that is still XP. I am on a HP Compaq 8200 Elite SFF PC Windows 7 Professional. I have attached a screen shot of the error I receive when I try to access the folder when it is password protected. Please let me know if you have any suggestions or need more information.
