Final answer:
To prevent a host from joining an NLB cluster automatically and from responding to remote NLB commands, disable the 'Start with Windows' option and remote control capability in the NLB settings.
Step-by-step explanation:
You're referring to configurations for a Network Load Balancer (NLB) in a server environment. If you want to prevent a host from joining an NLB cluster automatically when the server starts, you should disable the option to 'Start with Windows' in the NLB properties. Additionally, to prevent the host from responding to remote NLB commands, you should configure the remote control options and disable remote control capability within the NLB Manager or through similar management tools provided by your server's operating system.
