SMB

Enabling SMB will make shared folders accessible by an operating system that supports the protocol. If you are using Windows Active Directory (hereafter referred to as "AD"), you can add your NAS to your AD domain.

  • Workgroup: This is the workgroup on your local area network that your NAS belongs to.
  • WINS server: Microsoft Windows Internet Name Service (WINS) is a NetBIOS name-to-IP-address mapping service. Window users will locate the system more easily on TCP/IP networks if the system has been configured to register with a WINS server.
  • Max protocol for Windows File Service: Here you can set the highest SMB level that will be supported by your ASUSTOR NAS depending on your network environment.
    • SMB 3: SMB 3 has been supported since Windows 8 and Windows Server 2012. It is the enhanced version of SMB 2.
    • SMB 2: SMB (Server Message Block) 2 has been supported since Windows Vista and is the enhanced version of SMB. SMB 2 adds the ability to compound multiple SMB actions into a single request to reduce the number of network packets and enhance performance.
  • Local Master Browser: After enabling this option, your NAS will, from your local area network, collect the names of all other computers in its workgroup.
  • Reminder: Enabling this feature may prevent your hard drives from going into hibernation.

  • Allow only NTLMv2 authentication: NTLMv2 stands for NT LAN Manager version 2. When this option is enabled, login to the shared folders by Microsoft Networking will only be allowed using NTLMv2 authentication. If the option is disabled, NTLM (NT LAN Manager) will be used by default and NTLMv2 can be negotiated by the client. The default setting is disabled.
  • Disable Opportunistic Locking: For networks that require multiple users concurrently accessing the same file such as database, it is suggested to disable Opportunistic Locking. To prevent one file being edited by multiple users simultaneously, such mechanism should be implemented in the document processing software (for example, Microsoft Office programs).
  • Enable debug logging: When this option is enabled, detailed logs will be stored for debugging purposes. Enabling this option affects system performance.

About Windows Active Directory

After successfully adding your NAS to your AD domain, you can then configure access rights using the Domain Users, Domain Groups and Shared Folders settings found in the Access Control system app. AD users can then use their own AD accounts to log in and access the NAS.
