NSA-2400 User’s Guide

V

A local user cannot access a share

• Check that the NSA is turned on and connected to the network. The local user should try 

to ping the NSA or use the NDU 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 if the share has an ANONMYOUS or EVERYONE access right. If the user is 

already logged into a share using her username and password, she will NOT be able to 
access a share that has ANONYMOUS CIFS or ANONYMOUS FTP only access rights 
(as these require ‘no login’). In this case she should log out and try to access the share 
again without logging in. See 

 for more details.

• 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. DENY always takes 

precedence. If you allow a user FULL access to a share but set his group to DENY, 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 NSA. 

He may need to disconnect existing CIFS connections as new CIFS connection may use 
previously-saved login information that may be different to NSA-2400 login.

• Check that the volume in which the share resides, exists and is not down or degraded. If 

the volume is down or degraded, then please see 

. 

• If the user is using DFS links, then he can only access the NSA using CIFS and not FTP.

V

A domain user can’t access a share.

In addition to the checks listed previously for local users, you can perform these checks for 
domain users.

• Check that the domain controller is turned on.

• Check that the NSA-2400 time is synchronized with the domain controller. If the NSA 

time is set manually, make sure that the domain controller is also set manually to the same 
time. If the NSA is using a time server, make sure the domain controller is using the same 
time server and refresh the time on both devices. You could use your domain controller as 
your time server if it has this function. Select Set My Own Timeserver and then enter the 
domain controller's IP address in Time Server Address. You can then in turn, set your 
domain controller to use another time server on the Internet so that its time is accurate with 
the rest of the world.
