Remove OK Cancel Apply OK Cancel Adding Members to Domain Groups

  14. Why Assign a Manager to a Group? • To enable you to: • Track who is responsible for groups • Delegate to the manager of the group the authority to add users to and remove users from the group • To distribute the administrative responsibility of adding users to groups to the people who request the group Manager Group

  15. Changing Group Scope Global to universal Domain local to universal Universal to global Universal to domain local Available in native mode Changing Group Type Security to distribution Distribution to security Available in native mode Modifying Groups • Deleting a Group • Deletes the group but not the objects that are members • Cannot restore a group and its permissions

  23. Why Use Group Strategies

  24. Guidelines for Planning a Group Strategy • Assign users with common job responsibilities to global groups • Create a domain local group for sharing resources • Add global groups that require access to resources to domain local groups • Use universal groups to grant access to resources in multiple domains • Use universal groups when membership is static

  25. Default Groups on Member Servers

  26. Default Groups in Active Directory

  27. When to Use Default Groups • Default groups are: • Created during the installation of the operating system or when services are added such as Active Directory or DHCP • Automatically assigned a set of user rights • Use Default groups to: • Control access to shared resources • Delegate specific domain-wide administration

  28. Examples of User Rights What Are User Rights?

  29. User Rights vs. Permissions User Rights: Actions on System Permissions: Actions on Object

  30. System Groups • System groups represent different users at different times • You can grant user rights and permissions to system groups, but you cannot modify or view the memberships • Group scopes do not apply to system groups • Users are automatically assigned to system groups whenever they log on or access a particular resource
