Chapter 12 Troubleshooting

NSA-2401 User’s Guide

• Leave the domain and re-join it.

V

 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.

V

A user can access a share but cannot access individual folders or files within 
the share.

Check the Access Control List (ACL) of read/write permissions associated with the share’s 
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).

V

I cannot make a backup.

• Check the logs to find the reason why the backup failed.

• You can also look at the Backup screen’s Last Run Result display.

• If you’re backing up to another NSA, another NSA, or a computer, check that it allows the 

NSA to write files to it. For a synchronization backup, the target must be another NSA or 
another compatible model.

• Check that enough space is available on the external disk. If there isn’t you may need to 

purge older backups or delete other files on the backup USB disk or NSA (see 

).

• Check that the NSA is not performing another backup job. Scheduler queues backups 

when a different backup is already going on at the time a backup is scheduled.

V

I cannot take a snapshot

• Check the logs. The NSA generates an alert log when an error occurs during the snapshot 

capture process. This log lists why the snapshot failed, for example, low disk space.
