CIFS Client Disconnection on File Read Description Cause Workaround CIFS client disconnection on file read. Extreme CIFS workload during controller failover. Client needs to reconnect and open the file again. CIFS Client General Disconnection Description Cause Workaround CIFS client disconnection. In case the system identified a general issue with the CIFS service, it will be automatically recovered but the failure will cause all users to be disconnected and the above event to be triggered. If this issue repeats frequently, contact Dell. CIFS Client Login Failure Description Cause Workaround CIFS client login failure. User supplied wrong password upon connection. Interactive users can retry with correct password. Applications and servers might need special attention as the user/password, which is usually set in a script or configuration file, has probably expired. CIFS Connection Failure Description Cause Workaround CIFS client share access denied. The user is unknown in the Active Directory server, and the NAS system mapped this user to a guest user. If the share does not allow guest access, the user receives an access denied alert. Ensure that the user is listed in the Active Directory server the NAS is using. Alternatively, you can remove the guest limitation for the share. If the user can now access the share as guest, the newly created files will be owned by the nobody/guest user. 156 Troubleshooting

Description
CIFS client disconnection.
Cause
In case the system identified a general issue with the CIFS service,
it will be automatically recovered but the failure will cause all users

Description
CIFS client login failure.
Cause
User supplied wrong password upon connection.

Description
CIFS client share access denied.
Cause
The user is unknown in the Active Directory server, and the NAS
system mapped this user to a guest user. If the share does not allow
guest access, the user receives an access denied alert.
Workaround
Ensure that the user is listed in the Active Directory server the
NAS is using. Alternatively, you can remove the guest limitation for
the share. If the user can now access the share as guest, the newly
created files will be owned by the nobody/guest user.
