20.6 Users Cannot Access the NAS

A local user cannot access a share.
• Check that the NAS is turned on and connected to the network. The local user should try to ping the
NAS or use the NAS Starter Utility to discover it.
• The local user should check that he entered his login name and password correctly.
• Check if the share exists and has the correct access settings for this user.
• Check the read/write permissions associated with specific files and/or folders. Account names added
to the list are linked to the files and folders that they are allowed to access, along with what kinds of
actions they are allowed to perform with those files and folders (delete, move, rename, and so on).
• The user's computer may already be connected to another of the NAS's shares using a different user
name and/or password. This can happen without the user realizing it if the user's computer
automatically connects to a share at logon. Right-click any other connected shares and click
Disconnect. Then re-attempt to connect to the desired share.
• Check if the shared folder is a subfolder of another (parent) share. Check that the parent share's
access rights do not conflict with the subfolder share. It is recommended that you do not create
subfolder shares.
• Check if the user belongs to a group with conflicting access rights. No Access always takes
precedence. If you allow a user Read/Write access to a share but set his group to No Access, then he
will NOT be able to access the share.
• The local user should check if there are any existing mapped network drives to the NAS. He may need
to disconnect existing CIFS connections as new CIFS connection may use previously-saved login
information that may be different to NAS login.
• Check that the array in which the share resides, exists and is not down or degraded. If the array is
down or degraded, see
• If the user is using DFS links, then he can only access the NAS using CIFS and not FTP.
• Check that the share has not been disabled.
I cannot import domain user or user group information even though testing of the connection to
the domain controller is OK.
• Check the NAS's DNS setting. The DNS server the NAS is using must be able to resolve the domain
controller's address. If the domain controller uses a private IP address, the NAS needs to use a private
DNS server. If the domain controller uses a public IP address, the NAS needs to use a public DNS
server.
• Leave the domain and re-join it.
A domain user can't access a share.
In addition to the checks listed previously for local users, check that the domain controller is turned on
and connected to the network.
