A server administrator wants to allow network client computers to register their hosts automatically. Which of the following services should the administrator enable?

FTP (File Transfer Protocol) is a protocol for transferring files between a client and server and has no functionality related to name or host registration.

Standard DNS does not accept automatic registrations from clients on its own - automatic host registration in DNS requires the additional Dynamic DNS (DDNS) update mechanism, which is a distinct configuration not implied by enabling DNS alone.

SMTP (Simple Mail Transfer Protocol) is used for routing and delivering email messages between mail servers and clients, and has no role in host name or address registration.

WINS is a Microsoft name registration and resolution service in which Windows clients automatically send a registration request containing their NetBIOS name and current IP address to the WINS server when they join the network. This dynamic self-registration eliminates manual host entry and keeps the name database current as clients obtain new addresses from DHCP.
