Enabling the NetBios name service

Beginning in ONTAP 9.4, the NetBIOS name service (NBNS) sometimes called Windows Internet Name Service (WINS) is disabled by default. Previously, CIFS-enabled storage virtual machines (SVMs) sent name registration broadcasts regardless of whether WINS was enabled on a network. To limit such broadcasts to configurations where NBNS is required, you must enable NBNS explicitly for new CIFS servers.

Before you begin

  • NBNS is enabled over UDP (port 137).

  • NBNS over IPv6 is not supported.

  1. Set the privilege level to advanced.
    set -privilege advanced
  2. Enable NBNS on a CIFS server.
    vserver cifs options  modify -vserver <vserver name> -is-nbns-enabled true
  3. Return to the admin privilege level. 
    set -privilege admin
