Which command would be used to search for all available workgroups/domains and NetBIOS names?

`nmblookup` is used to query specific NetBIOS names or perform name resolution, but it does not provide a comprehensive list of all available workgroups/domains on its own.

The `findsmb` utility is designed to scan the local network segment and enumerate all responding SMB/CIFS servers, displaying their NetBIOS names, workgroup/domain membership, and IP addresses, effectively showing available workgroups and domains.

`smbget` is a client utility used for downloading files from SMB/CIFS shares and is not intended for network discovery.

`smbclient` is an interactive command-line client for accessing SMB/CIFS shares, browsing directories, and transferring files, not for broad network workgroup discovery.
