Option User Action
Local master browser Select this option to use the NAS as a local master browser. A local
master browser is responsible for maintaining the list of devices in
a specific workgroup on a Microsoft network.
Important
To use the NAS as local master browser, specify
the workgroup name when configuring Microsoft
networking. The default workgroup in Windows is
"workgroup".
Allow only NTLMSSP authentication Select this option to authenticate clients using only NT LAN
Manager Security Support Provider.
When this option is deselected, QTS uses NT LAN Manager
(NTLM).
Name resolve priority Select a name service to use for name resolution.
The default service is DNS only.
If a WINS server is specified, Try WINS then DNS is selected by
default.
Atlernative login Style Select this option to change how usernames are structured when
accessing FTP, AFP, or File Station services.
After selecting this option, users can access NAS services using
Domain\Username, instead of Domain+Username.
Automatically register in DNS Select this option to register the NAS on the DNS server. If the NAS
IP address changes, the NAS automatically updates the IP address
on the DNS server.
This option is only available if AD authentication is enabled.
Enable trusted domains Select this option to join users from trusted AD domains.
This option is only available if AD authentication is enabled.
Enable Asynchronous I/O Select this option to improve the Samba performance using
asynchronous I/O.
Asynchronous I/O refers to the I/O behavior on the CIFS protocol
layer. This is different from the synchronous I/O feature found in
the shared folder settings, which only applies to specific shared
folders on the file system level.
Tip
To prevent power interruption, use a UPS when
asynchronous I/O is enabled.
Enable WS-Discovery to help SMB
clients discover the NAS.
Select this option to enable Web Services Dynamic Discovery (WS-
Discovery). WS-Discovery makes the NAS visible in File Explorer on
Windows 10 computers.
Highest SMB version Select the highest SMB protocol version used in your networking
operation.
Use the default SMB version if you are unsure about this setting.
Note
Selecting SMB3 will also include SMB3.1 and
SMB3.1.1.
