The tool that a security administrator would MOST likely use to confirm suspicions of unnecessary services running on a server is Nmap.

Nmap is a network exploration and security auditing tool. It can be used to discover hosts and services on a computer network, thus providing insight into which services are running on a particular server.

Using Nmap, a security administrator can perform a port scan of the server in question to identify which ports are open and which services are running. The administrator can then compare the identified services with the known services required by the server's intended use. Any services that are running but not required for the server's intended use can be identified as unnecessary and potentially pose a security risk.

Wireshark is a network protocol analyzer that can capture network traffic and display it in a human-readable format. While it can be used to identify the types of traffic passing through a network, it is not as effective as Nmap in identifying unnecessary services running on a server.

Autopsy is a digital forensics platform used for analyzing hard drives and mobile devices. It is not a suitable tool for identifying unnecessary services running on a server.

DNSEnum is a DNS enumeration tool used to gather information about DNS nameservers and their associated domains. It is not a suitable tool for identifying unnecessary services running on a server.
