In addition to these three scopes, the default groups in the Builtin container have a group scope of Builtin Local. This group scope and group type cannot be changed. The following table lists the three group scopes and more information about each scope for a security group. Local groups on computers in the same domain, excluding built-in groups that have well-known SIDs. Special identities are generally referred to as groups.
Special identity groups do not have specific memberships that can be modified, but they can represent different users at different times, depending on the circumstances. For information about all the special identity groups, see Special Identities. Default groups, such as the Domain Admins group, are security groups that are created automatically when you create an Active Directory domain.
You can use these predefined groups to help control access to shared resources and to delegate specific domain-wide administrative roles. Many default groups are automatically assigned a set of user rights that authorize members of the group to perform specific actions in a domain, such as logging on to a local system or backing up files and folders. For example, a member of the Backup Operators group has the right to perform backup operations for all domain controllers in the domain.
When you add a user to a group, the user receives all the user rights that are assigned to the group and all the permissions that are assigned to the group for any shared resources. Default groups are located in the Builtin container and in the Users container in Active Directory Users and Computers.
The Builtin container includes groups that are defined with the Domain Local scope. The Users includes contains groups that are defined with Global scope and groups that are defined with Domain Local scope. You can move groups that are located in these containers to other groups or organizational units OU within the domain, but you cannot move them to other domains.
Some of the administrative groups that are listed in this topic and all members of these groups are protected by a background process that periodically checks for and applies a specific security descriptor. This descriptor is a data structure that contains security information associated with a protected object. This process ensures that any successful unauthorized attempt to modify the security descriptor on one of the administrative accounts or groups will be overwritten with the protected settings.
The security descriptor is present on the AdminSDHolder object. This means that if you want to modify the permissions on one of the service administrator groups or on any of its member accounts, you must modify the security descriptor on the AdminSDHolder object so that it will be applied consistently. Be careful when you make these modifications because you are also changing the default settings that will be applied to all of your protected administrative accounts. The following tables provide descriptions of the default groups that are located in the Builtin and Users containers in each operating system.
Members of this group can remotely query authorization attributes and permissions for resources on the computer. The Access Control Assistance Operators group applies to versions of the Windows Server operating system listed in the Active Directory default security groups by operating system version.
The Account Operators group grants limited account creation privileges to a user. Members of this group can create and modify most types of accounts, including those of users, local groups, and global groups, and members can log in locally to domain controllers. Members of the Account Operators group cannot manage the Administrator user account, the user accounts of administrators, or the Administrators , Server Operators , Account Operators , Backup Operators , or Print Operators groups.
Members of this group cannot modify user rights. The Account Operators group applies to versions of the Windows Server operating system listed in the Active Directory default security groups by operating system version.
By default, this built-in group has no members, and it can create and manage users and groups in the domain, including its own membership and that of the Server Operators group. This group is considered a service administrator group because it can modify Server Operators, which in turn can modify domain controller settings.
As a best practice, leave the membership of this group empty, and do not use it for any delegated administration. This group cannot be renamed, deleted, or moved. Allow log on locally : SeInteractiveLogonRight. Members of the Administrators group have complete and unrestricted access to the computer, or if the computer is promoted to a domain controller, members have unrestricted access to the domain.
The Administrators group applies to versions of the Windows Server operating system listed in the Active Directory default security groups by operating system version. The Administrators group has built-in capabilities that give its members full control over the system.
This built-in group controls access to all the domain controllers in its domain, and it can change the membership of all administrative groups. Membership can be modified by members of the following groups: the default service Administrators, Domain Admins in the domain, or Enterprise Admins. This group has the special privilege to take ownership of any object in the directory or any resource on a domain controller.
This account is considered a service administrator group because its members have full access to the domain controllers in the domain. Default user rights changes: Allow log on through Terminal Services existed in Windows Server , and it was replaced by Allow log on through Remote Desktop Services. Remove computer from docking station was removed in Windows Server R2.
Adjust memory quotas for a process : SeIncreaseQuotaPrivilege. Access this computer from the network : SeNetworkLogonRight. Back up files and directories : SeBackupPrivilege. Bypass traverse checking : SeChangeNotifyPrivilege. Change the system time : SeSystemTimePrivilege. Change the time zone : SeTimeZonePrivilege. Create a pagefile : SeCreatePagefilePrivilege.
Create global objects : SeCreateGlobalPrivilege. Enable computer and user accounts to be trusted for delegation : SeEnableDelegationPrivilege. Force shutdown from a remote system : SeRemoteShutdownPrivilege. Impersonate a client after authentication : SeImpersonatePrivilege. Load and unload device drivers : SeLoadDriverPrivilege. Log on as a batch job : SeBatchLogonRight.
Manage auditing and security log : SeSecurityPrivilege. Modify firmware environment values : SeSystemEnvironmentPrivilege. Perform volume maintenance tasks : SeManageVolumePrivilege. Profile system performance : SeSystemProfilePrivilege. Remove computer from docking station : SeUndockPrivilege. Restore files and directories : SeRestorePrivilege. Shut down the system : SeShutdownPrivilege.
Take ownership of files or other objects : SeTakeOwnershipPrivilege. The purpose of this security group is to manage a RODC password replication policy. This group has no members by default, and it results in the condition that new Read-only domain controllers do not cache user credentials.
Members of the Backup Operators group can back up and restore all files on a computer, regardless of the permissions that protect those files. Backup Operators also can log on to and shut down the computer. By default, this built-in group has no members, and it can perform backup and restore operations on domain controllers. Its membership can be modified by the following groups: default service Administrators, Domain Admins in the domain, or Enterprise Admins.
It cannot modify the membership of any administrative groups. While members of this group cannot change server settings or modify the configuration of the directory, they do have the permissions needed to replace files including operating system files on domain controllers. Because of this, members of this group are considered service administrators. The Backup Operators group applies to versions of the Windows Server operating system listed in the Active Directory default security groups by operating system version.
Members of the Cert Publishers group are authorized to publish certificates for User objects in Active Directory. The Cert Publishers group applies to versions of the Windows Server operating system listed in the Active Directory default security groups by operating system version.
Members of the Cloneable Domain Controllers group that are domain controllers may be cloned. In Windows Server R2 and Windows Server , you can deploy domain controllers by copying an existing virtual domain controller.
In a virtual environment, you no longer have to repeatedly deploy a server image that is prepared by using sysprep. This security group was introduced in Windows Server , and it has not changed in subsequent versions. Members of this group are authorized to perform cryptographic operations.
The Cryptographic Operators group applies to versions of the Windows Server operating system listed in the Active Directory default security groups by operating system version. This security group was introduced in Windows Vista Service Pack 1, and it has not changed in subsequent versions. This group contains a variety of high-privilege accounts and security groups.
Microsoft Component Object Model COM is a platform-independent, distributed, object-oriented system for creating binary software components that can interact.
Distributed Component Object Model DCOM allows applications to be distributed across locations that make the most sense to you and to the application. This group appears as a SID until the domain controller is made the primary domain controller and it holds the operations master role also known as flexible single master operations or FSMO. The Distributed COM Users group applies to versions of the Windows Server operating system listed in the Active Directory default security groups by operating system version.
They are permitted to perform dynamic updates on behalf of other clients such as DHCP servers. Adding clients to this security group mitigates this scenario. However, to protect against unsecured records or to permit members of the DnsUpdateProxy group to register records in zones that allow only secured dynamic updates, you must create a dedicated user account and configure DHCP servers to perform DNS dynamic updates by using the credentials of this account user name, password, and domain.
Multiple DHCP servers can use the credentials of one dedicated user account. Members of the Domain Admins security group are authorized to administer the domain. By default, the Domain Admins group is a member of the Administrators group on all computers that have joined a domain, including the domain controllers.
The Domain Admins group is the default owner of any object that is created in Active Directory for the domain by any member of the group.
If members of the group create other objects, such as files, the default owner is the Administrators group. The Domain Admins group controls access to all domain controllers in a domain, and it can modify the membership of all administrative accounts in the domain. Membership can be modified by members of the service administrator groups in its domain Administrators and Domain Admins , and by members of the Enterprise Admins group.
This is considered a service administrator account because its members have full access to the domain controllers in a domain. The Domain Admins group applies to versions of the Windows Server operating system listed in the Active Directory default security groups by operating system version.
This group can include all computers and servers that have joined the domain, excluding domain controllers. By default, any computer account that is created automatically becomes a member of this group.
The Domain Computers group applies to versions of the Windows Server operating system listed in the Active Directory default security groups by operating system version. This is just wrong. A local domain group can contain universal, global and local domain groups, so yes, you can make a universal group a member of a local domain group, and yes, you can make a global group a member of a local domain group.
Your mistake is in making your security groups email enabled. This is what distribution groups are for. Since a universal group can contain both universal and global groups, you could have created a universal distribution group and added your global security groups to that.

I've always just used universal groups and never had any problems and was wondering why use something like a global group instead of a universal group.
Also, what is the piont of the domain local group? I've never used it and I'm having a hard time based on what I've read in telling the differences. Wednesday, July 1, PM. You can give universal security groups rights and permissions on resources in any domain in the forest. In all those locations, you can give a global group rights and permissions and the global group can become a member of local groups.
However, a global group can contain user accounts that are only from its own domain. You can give domain local security groups rights and permissions on resources that reside only in the same domain where the domain local group is located.
Hi, I am wondering about the use of Universal groups in Server We have have one tree and one domain and don't forsee any additonal domains or trees or federation or anything in the nearby future even though one can never be sure ;-. We have learned that best practise is to put users in a global group and then put the global groups in a domain local group and finally to use the DL group to assign permission to folders in the filesystem.
Now, why can't we just skip the extra DL groups and use Universal groups all the way. That is put the user into a universal group and then use that group to assign permissions in the filesystem or in the AD as well?
We have a lot of groups and would be nice if we didn't have to use that extra layer of DL groups. In the Enter User or Group names field, type a user or group that exists in the domain or as a local user or group on the computer. Then click Check Names to resolve it to the full existent name. Click Find to open the standard Select Users or Groups dialog box. Then select domain users or groups. Select this check box to assign an expiration date for the permissions set for this user or group.
When selected, the date box is enabled. Set the date, and permissions will expire at the end of the date specified. Select this check box to assign a time period in which the policy must be refreshed for this user or group.
When selected, the time period box is enabled. Set the number of days or hours, and at the end of the specified time period, the user or group will not be able to connect if the policy is not refreshed.
