Check that the permissions are correctly set for the shared folder. If you are trying to connect with a user who is a member of several different groups and if any of these groups have been assigned specific permissions for the share then the most restrictive permissions will apply for this user. If you are working on Windows in a workgroup environment, then you need to make sure that you create a user account with the exact same name and password on the Ethernet Disk as the current logged user on your Windows client.
If you are working on Windows in a domain environment that uses Kerberos authentication you need to make sure that the time settings on the Ethernet Disk and the domain server(s) do not differ more than 5 minutes. If the difference is more than 5 minutes, then access will not be granted. The reason for this is that the Ethernet Disk does not support automatic time synchronization with domain controllers. You need to manually keep the time updated on the Ethernet Disk or to adjust the time skew on the domain server(s) to accept a greater difference than 5 minutes. Alternatively, you can also use any of the previous Windows authentication protocols (NTLM or NTLM2).
TO CHANGE THE KERBEROS TIME SKEW ON THE SERVER:
1. From the Start menu, go to Settings, click Control Panel, double-click Administrative Tools, and then double-click Domain Security Policy.
2. Expand Security Settings, Account Policies, and Kerberos Policy.
3. Right-click Maximum tolerance for computer clock synchronization.
4. Click Security.
5. In the Security Policy dialog box, change the maximum tolerance variable.
