Final answer:
The default group in Active Directory is the Domain Users group, which includes all user accounts created within a domain. It simplifies user management and allows for consistent settings to be applied to all users.
Step-by-step explanation:
The default group in Active Directory is called the Domain Users group. It is a built-in group that includes all user accounts created within a domain. This group has certain default permissions and can be used to assign common rights and permissions to all users in the domain.
For example, if you want to allow all users in the domain to access a specific shared folder, you can assign permissions to the Domain Users group instead of individually assigning permissions to each user account.
The Domain Users group can be useful for simplifying user management and applying consistent settings to all users within a domain.
