Which smb.conf configuration keyword determines the hostname resolution order?

`use ads` is a parameter related to Active Directory integration, not hostname resolution order.

The `name resolve order` parameter explicitly defines the order in which Samba attempts to resolve NetBIOS names and hostnames, such as using `lmhosts`, `host`, `wins`, and `bcast`. This allows administrators to customize the name resolution priority for Samba services.

`nsswitch.conf` is a system-wide configuration file for name service lookups on Unix-like systems, but Samba uses its own `name resolve order` for NetBIOS/hostname resolution within its `smb.conf`.

`resolv.conf` is a system-wide configuration file for DNS resolution, not a specific Samba keyword for defining its internal hostname resolution order.
