Active Directory Groups - What are the Different Types of Groups?

Summary

Active Directory (AD) groups are essential for efficient network management, enabling administrators to manage user accounts and permissions centrally. The groups can be categorized into security and distribution groups, each serving distinct purposes. Security groups streamline permission assignments, while distribution groups facilitate email communication. Group scopes—Universal, Global, and Domain Local—determine the membership and access levels. Local groups provide flexibility independent of domain controllers. Additionally, Active Directory supports converting between group types under specific conditions, enhancing management capabilities. Overall, these features simplify administration and enhance resource access within organizations.
