This message occurs when the NetBIOS Name Service receives more than 25 IP addresses for a name registration request. This is typically caused because of an upgrade from a previous release that had more than 25 IP addresses configured for a Vserver and WINS was configured. In such a scenario, clients might not be able to access data because some of the IP addresses might not have registered with WINS.
- Corrective Action
If there are more than 25 IP addresses configured for a Vserver, modify the "nbns-enabled-lifs" CIFS option to no more than a maximum of 25 LIFs by using the 'vserver cifs options modify -vserver <vserver> -nbns-enabled-lifs' command in advanced privilege mode when the effective cluster version is Data ONTAP 9.0 or later. In a mixed-mode cluster with a node running Data ONTAP 8.3, do not configure more than 25 LIFs per Vserver because of the following WINS server limitation: https://www.microsoft.com/resources/documentation/windowsnt/4/server/reskit/en-us/net/sur_wins.mspx
