Overview

Windows Server 2012 is a Microsoft server operating system in the Windows Server family (introduced in 2012) that delivers enterprise services such as Active Directory, file services, and Kerberos-based authentication. As an aging but widely deployed platform, it remains central to many IT environments, making secure authentication and timely migration important; recent security moves like phasing out RC4 in Kerberos directly impact its Kerberos-based security posture.
