And use global groups if you have trust universal groups if you don t care about trust.
Active directory security groups domain local global universal.
A global group can be used to assign permissions for access to resources in any domain.
Members from any domain may be added.
Domain security groups with domain local scope describe the low level permissions or user rights to which they are assigned.
The group is authorized to make schema changes in active directory.
The short answer is that domain local groups are the only groups that can have members from outside the forest.
In addition the scope can both contain and be a member of domain local groups from the same domain.
Domain local groups can contain users domain universal and domain global groups from any domain as well as domain local groups from the same domain.
These groups can only be used by systems in the same domain.
The differences between these are listed below.
Domain local groups can be a member of domain local groups from the same domain.
This might still be wrong.
A domain local group cannot be nested within a global or a universal group.
The illustration above shows that users also computers of domain a can become members of one or more universal groups of domain b.
Universal groups can be nested within domain local groups and within other universal groups in any domain.
It is a universal group if the domain is in native mode.
Members can be added only from the domain in which the global group was created.
Can be a member of any domain local group in the same domain.
By default the only member of the group is the administrator account for the forest root domain.
The domain local scope can contain user accounts universal groups and global groups from any domain.
There are three group scopes and they are domain local global and universal.
Domain local groups cangrant accessto resources on the same domain.
There is an option to nest universal groups via a trusted domain of the same forest with users computers domain local groups or global groups.
The global scope can contain user accounts and global groups from the same domain and can be a member of universal and domain local groups in any domain.
Domain local groups may contain accounts global groups and universal groups from any domain as well as domain local groups from the same domain.
Stored on the local sam local computer use for security settings that apply just to this one machine.
Universal security groups are most often used to assign permissions to related resources in multiple domains.
Use domain local groups to grant access to resources such as you file systems.
