Windows systems that take part in Kerberos authentication, such as domain controllers and domain-joined servers and workstations, are the places to look. The sources do not give the affected builds or any configuration needed. An attacker needs a valid account first, so systems with no domain accounts exposed to untrusted users are lower risk.
