Which service must be running to support name resolution in a Samba environment?

In a Samba environment, the service that must be running to support name resolution is nmbd. This service provides NetBIOS name service over the network, allowing for the resolution of NetBIOS names to IP addresses and vice versa. When clients or servers communicate within a network, they often use NetBIOS names. The nmbd daemon acts as a name server and a browser service that manages the list of available resources and hosts in a local network, which is crucial for ensuring that systems can find each other by name rather than just by IP address.

While smbd handles file and print services, and winbind is used for integrating UNIX/Linux systems with Windows authentication, neither of those services is responsible for name resolution. The "daemon" option is too vague and does not refer to any specific service related to Samba. Thus, nmbd is essential for enabling seamless name resolution within the Samba framework, facilitating easier resource access and network communication.
