Default groups in windows 2003

For Active Directory, there are two types of administrative responsibilities:. Data administrators Responsible for maintaining the data that is stored in AD DS and on domain member servers and workstations. Groups are used to collect user accounts, computer accounts, and other groups into manageable units.

Working with groups instead of with individual users helps simplify network maintenance and administration. Distribution groups can be used only with email applications such as Exchange Server to send email to collections of users. Distribution groups are not security enabled, which means that they cannot be listed in discretionary access control lists DACLs.

Security groups can provide an efficient way to assign access to resources on your network. By using security groups, you can:. User rights are assigned to a security group to determine what members of that group can do within the scope of a domain or forest. For example, a user who is added to the Backup Operators group in Active Directory has the ability to back up and restore files and directories that are located on each domain controller in the domain. This is possible because, by default, the user rights Backup files and directories and Restore files and directories are automatically assigned to the Backup Operators group.

Therefore, members of this group inherit the user rights that are assigned to that group. You can use Group Policy to assign user rights to security groups to delegate specific tasks. Permissions are different than user rights. Permissions are assigned to the security group for the shared resource. Permissions determine who can access the resource and the level of access, such as Full Control. Some permissions that are set on domain objects are automatically assigned to allow various levels of access to default security groups, such as the Account Operators group or the Domain Admins group.

Security groups are listed in DACLs that define permissions on resources and objects. When assigning permissions for resources file shares, printers, and so on , administrators should assign those permissions to a security group rather than to individual users.

The permissions are assigned once to the group, instead of several times to each individual user. Each account that is added to a group receives the rights that are assigned to that group in Active Directory, and the user receives the permissions that are defined for that group.

Like distribution groups, security groups can be used as an email entity. Sending an email message to the group sends the message to all the members of the group. Groups are characterized by a scope that identifies the extent to which the group is applied in the domain tree or forest.

The scope of the group defines where the group can be granted permissions. The following three group scopes are defined by Active Directory:. 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.

Article Summary Domain Group Policies give the administrator great control over its domain users by enhancing security levels and restricting access to specific areas of the operating system. Back to Windows Server Section Windows Group Policies allow the administrators to manage a group of people accessing a resource efficiently.

Right-click the domain name and select Properties from the menu that appears. The properties window of the domain appears. A new group policy object appears below the Default Domain Policy in the Group Policy tab, as shown below: Once you rename this group policy, you can either double-click on it, or select it and click Edit.

Active Directory Tombstone Lifetime Modification. Universal groups can be converted to global or domain local groups, and global and domain local groups can be converted to universal groups.

However, global groups cannot be converted directly to domain local groups and vice versa. The rules governing this are much easier than they first appear. Simply put, you cannot convert from one group type to another if the current membership of the group that is being converted is not compatible with the membership allowed for the target scope. For example, a universal security group cannot have a domain local group as a member.

Can be changed to a global group as long as no group members are other universal groups, or user, computer, or global group accounts from any domain other than the one in which the global group will exist. Can be changed to a universal group as long as the group is not a member of any other global group. You've seen how groups can have other groups as members. This concept is known as group nesting. Groups can be nested to help reduce management overhead.

The type of nesting you can perform is determined by the domain's functional level. If the domain functional level is set to Windows native or Windows Server , the following groups have additional nesting capability:. The nesting occurs in addition to the basic security group memberships that are permitted at the Windows mixed functional level. Group nesting is pictured in Figure 3. If a user moves from a tier 2 position in desktop support to the Windows server team, removing the user from one group and adding the user to another group automatically adjusts the permissions and rights the user is receiving from several groups.

In the first example, the user is a member of the Tier2 global group, which is itself a member of the Desktop Support global group. This group is in turn nested in the IT global group.

Thus, any per-. Continued missions or rights granted to the IT, Desktop Support, and Tier2 groups will be given to the user. When the user's account is moved, the user becomes a member of the Windows global group. The move will cause the user to lose all of the permissions and rights that were granted from the Tier2 and Desktop Support global groups.

The Windows group is a member of the Software global group, which is nested in the Server Support global group. Finally, Server Support is a member of the IT global group. The user's new group membership will bring all of the permissions and rights granted to the IT, Server Support, Software, and Windows global groups.

You can now set the Computer Configuration or User Configuration policies as desired. This example takes User Configuration setting.

Double-click the settings for the policy that you want to modify from the right panel. The properties window of the setting appears as shown in the below screenshot:. Once you click on ' OK ', the local policy that you have applied will take effect and all the users who would log on to this computer will not be able to see the Run menu item of the Start menu.

This completes our Local Group Policy configuration section. Next section covers Domain Group Policies , that will help you configure and control user access throughout the Active Directory Domain. Group Policies are an Administrator's best friend. Group Policies can control every aspect of a user's desktop, providing enhanced security measures and restricting access to specified resouces.

Group policies can be applied to a local server , as shown on this article, or to a whole domain.
