The DNS Server plays a crucial role in a Windows Server environment by resolving hostnames to IP addresses. This function is foundational for enabling communication between devices over a network. When a user or application attempts to connect to a server or website, it typically does so using a human-readable hostname (like www.example.com). The DNS Server translates this hostname into the corresponding IP address, which is used to actually route the network traffic to the correct location.

This process is essential for the functionality of various network services, as most applications and users prefer to use easy-to-remember names rather than numeric IP addresses. Proper DNS resolution ensures that resources are accessible and that network communications are seamless.

The other functions mentioned do not pertain to the direct responsibilities of a DNS Server. For instance, managing user accounts is generally the role of Active Directory, firewall protection is typically handled by specific security software or hardware devices, and email routing is managed by mail server applications, not by DNS itself. Thus, B is the correct answer as it accurately describes the primary function of a DNS Server in a Windows Server environment.
