Assign a NetBIOS Name Server
Microsoft’s Common Internet File System (SMB/CIFS) requires a NetBIOS Name Server
(NBNS) for queries to map a NetBIOS name to IP addresses. WebVPN will use NetBIOS to
access or allow file sharing through a WebVPN connection. The initial NBNS server
configured will be the primary server, and all subsequent servers will be considered
redundant backups. The ASA 55X0 supports three NBNS server entries.
NBNS entries are assigned in WebVPN mode nested in global-configuration mode. To assign
an NBNS entry, use the following command:
nbns-server {ipaddr or hostname} [master] [timeout timeout] [retry retries]
Table 13-10 describes the parameters for the nbns-server command.
