The coverage also distinguishes DNS-hosting servers from ordinary workstations and highlights domain controllers as high-value infrastructure because they commonly provide DNS in Active Directory environments. This archive is primarily relevant to enterprise IT administrators responsible for Windows Server, Active Directory, and security update processes.
