Download the RSAT version that matches the bitness of your operating system. Double-click the file to start installation:. Or install the MSU file from in the command prompt in the quiet mode:.
Then you just have to activate the necessary options. To do it:. After the administrative tools have been installed, you will see a link to Active Directory Users and Computers snap-in in the Administrative Tools section of the Control Panel. The name active directory users and computers for windows 10 the domain controller you are connected to is windowa the top of the console.
You can connect to another AD domain controller or another domain by clicking the console root and selecting the Change option you want in the context menu. A domain administrator may create containers OUs based on active directory users and computers for windows 10 physical or logical active directory users and computers for windows 10 structure. Using a context menu, you can create new AD objects users, groups, computers, OUs, contactsrename, move, or delete objects.
Depending on the selected object type, context menu options may vary. You can use the Search context menu to search for objects dirsctory AD.
In ADUC, you can view or change domain object properties. For example, you can open user properties and edit its settings. Some user properties are located in the corresponding tabs, and the full list of user attributes is available in the AD Attribute Editor tab. You can add a separate tab with an AD user photo.

Install Active Directory Users and Computers (ADUC) Snap-in on Windows 10/11 | Windows OS Hub.
After the Guest account is enabled, it is a best practice to monitor this account frequently to ensure that other users cannot use services and other resources, such as resources that were unintentionally left available by a previous user. Do not use the Guest account when the server has external network access or access to other computers. If you decide to enable the Guest account, be sure to restrict its use, and to change the password regularly.
As with the Administrator account, you might want to rename the account as an added security precaution. In addition, an administrator is responsible for managing the Guest account. The administrator monitors the Guest account, disables the Guest account when it is no longer in use, and changes or removes the password as needed.
The HelpAssistant account is a default local account that is enabled when a Remote Assistance session is run. This account is automatically disabled when no Remote Assistance requests are pending. HelpAssistant is the primary account that is used to establish a Remote Assistance session. The Remote Assistance session is used to connect to another computer running the Windows operating system, and it is initiated by invitation.
For solicited remote assistance, a user sends an invitation from their computer, through e-mail or as a file, to a person who can provide assistance. This group includes all users who sign in to a server with Remote Desktop Services enabled. This group includes all users who connect to the computer by using a remote desktop connection. This group is a subset of the Interactive group. For the Windows Server operating system, Remote Assistance is an optional component that is not installed by default.
You must install Remote Assistance before it can be used. No Safe to move out of default container? Can be moved out, but we do not recommend it. Safe to delegate management of this group to non-Service admins? This account cannot be deleted, and the account name cannot be changed.
Windows Server Kerberos authentication is achieved by the use of a special Kerberos ticket-granting ticket TGT enciphered with a symmetric key. This key is derived from the password of the server or service to which access is requested. Like any privileged service accounts, organizations should change these passwords on a regular schedule. The password for the KDC account is used to derive a secret key for encrypting and decrypting the TGT requests that are issued.
The password for a domain trust account is used to derive an inter-realm key for encrypting referral tickets. Resetting the password requires you either to be a member of the Domain Admins group, or to have been delegated with the appropriate authority.
In addition, you must be a member of the local Administrators group, or you must have been delegated the appropriate authority. It is also a best practice to reset the KRBTGT account password to ensure that a newly restored domain controller does not replicate with a compromised domain controller. In this case, in a large forest recovery that is spread across multiple locations, you cannot guarantee that all domain controllers are shut down, and if they are shut down, they cannot be rebooted again before all of the appropriate recovery steps have been performed.
After you reset the KRBTGT account, another domain controller cannot replicate this account password by using an old password. An organization suspecting domain compromise of the KRBTGT account should consider the use of professional incident response services. The impact to restore the ownership of the account is domain-wide, labor intensive, and should be undertaken as part of a larger recovery effort.
Resetting the KRBTGT password is similar to renewing the root CA certificate with a new key and immediately not trusting the old key, resulting in almost all subsequent Kerberos operations will be affected. All the TGTs that are already issued and distributed will be invalid because the DCs will reject them.
When the password changes, the tickets become invalid. All currently authenticated sessions that logged on users have established based on their service tickets to a resource such as a file share, SharePoint site, or Exchange server are good until the service ticket is required to reauthenticate.
Because it is impossible to predict the specific errors that will occur for any given user in a production operating environment, you must assume all computers and users will be affected. Rebooting a computer is the only reliable way to recover functionality as this will cause both the computer account and user accounts to log back in again.
After an account is successfully authenticated, the RODC determines if a user's credentials or a computer's credentials, can be replicated from the writable domain controller to the RODC by using the Password Replication Policy.
Each default local account in Active Directory has several account settings that you can use to configure password settings and security-specific information, as described in the following table:. Account is disabled Prevents the user from signing in with the selected account. As an administrator, you can use disabled accounts as templates for common user accounts.
Smart card is required for interactive logon Requires that a user has a smart card to sign on to the network interactively. The user must also have a smart card reader attached to their computer and a valid personal identification number PIN for the smart card.
When this attribute is applied on the account, the effect is as follows: The attribute only restricts initial authentication for interactive logon and Remote Desktop logon. When interactive or Remote Desktop logon requires a subsequent network logon, such as with a domain credential, an NT Hash provided by the domain controller is used to complete the smartcard authentication process.
This invalidates the use of any previously configured passwords for the account. The value does not change after that unless a new password is set or the attribute is disabled and re-enabled.
Accounts with this attribute cannot be used to start services or run scheduled tasks. Account is trusted for delegation Lets a service running under this account to perform operations on behalf of other user accounts on the network. A service running under a user account also known as a service account that is trusted for delegation can impersonate a client to gain access to resources, either on the computer where the service is running or on other computers.
For example, in a forest that is set to the Windows Server functional level, this setting is found on the Delegation tab.
It is available only for accounts that have been assigned service principal names SPNs , which are set by using the setspn command from Windows Support Tools. This setting is security-sensitive and should be assigned cautiously. Account is sensitive and cannot be delegated Gives control over a user account, such as for a Guest account or a temporary account.
This option can be used if this account cannot be assigned for delegation by another account. Do not require Kerberos preauthentication Provides support for alternate implementations of the Kerberos protocol. Because preauthentication provides additional security, use caution when enabling this option. Domain controllers running Windows or Windows Server can use other mechanisms to synchronize time. DES is not enabled by default in Windows Server operating systems starting with Windows Server R2, nor in Windows client operating systems starting with Windows 7.
If your environment requires DES, then this setting might affect compatibility with client computers or services and applications in your environment. After the default local accounts are installed, these accounts reside in the Users container in Active Directory Users and Computers.
You can use Active Directory Users and Computers to assign rights and permissions on a given local domain controller, and that domain controller only, to limit the ability of local users and groups to perform certain actions. A right authorizes a user to perform certain actions on a computer, such as backing up files and folders or shutting down a computer. In contrast, an access permission is a rule that is associated with an object, usually a file, folder, or printer that regulates which users can have access to the object and in what manner.
For more information about creating and managing local user accounts in Active Directory, see Manage Local Users. You can also use Active Directory Users and Computers on a domain controller to target remote computers that are not domain controllers on the network.
You can obtain recommendations from Microsoft for domain controller configurations that you can distribute by using the Security Compliance Manager SCM tool.
For more information, see Microsoft Security Compliance Manager. Some of the default local user accounts are protected by a background process that periodically checks and applies a specific security descriptor, which is a data structure that contains security information that is associated with a protected object. This means, when you want to modify the permissions on a service administrator group or on any of its member accounts, you are also required to modify the security descriptor on the AdminSDHolder object.
This approach ensures that the permissions are applied consistently. Be careful when you make these modifications, because this action can also affect the default settings that are applied to all of your protected administrative accounts. Restricting and protecting domain accounts in your domain environment requires you to adopt and implement the following best practices approach:.
Member accounts in the Administrators, Domain Admins, and Enterprise Admins groups in a domain or forest are high-value targets for malicious users. It is a best practice to strictly limit membership to these administrator groups to the smallest number of accounts in order to limit any exposure. Restricting membership in these groups reduces the possibility that an administrator might unintentionally misuse these credentials and create a vulnerability that malicious users can exploit.
Moreover, it is a best practice to stringently control where and how sensitive domain accounts are used. Restrict the use of Domain Admins accounts and other administrator accounts to prevent them from being used to sign in to management systems and workstations that are secured at the same level as the managed systems. When administrator accounts are not restricted in this manner, each workstation from which a domain administrator signs in provides another location that malicious users can exploit.
To provide for instances where integration challenges with the domain environment are expected, each task is described according to the requirements for a minimum, better, and ideal implementation. As with all significant changes to a production environment, ensure that you test these changes thoroughly before you implement and deploy them. Then stage the deployment in a manner that allows for a rollback of the change in case technical issues occur. Restrict Domain Admins accounts and other sensitive accounts to prevent them from being used to sign in to lower trust servers and workstations.
Restrict and protect administrator accounts by segregating administrator accounts from standard user accounts, by separating administrative duties from other tasks, and by limiting the use of these accounts.
Create dedicated accounts for administrative personnel who require administrator credentials to perform specific administrative tasks, and then create separate accounts for other standard user tasks, according to the following guidelines:. Privileged account. Allocate administrator accounts to perform the following administrative duties only:.
Create separate accounts for domain administrators, enterprise administrators, or the equivalent with appropriate administrator rights in the domain or forest. Use accounts that have been granted sensitive administrator rights only to administer domain data and domain controllers. Create separate accounts for administrators that have reduced administrative rights, such as accounts for workstation administrators, and accounts with user rights over designated Active Directory organizational units OUs.
Create multiple, separate accounts for an administrator who has several job responsibilities that require different trust levels. Set up each administrator account with different user rights, such as for workstation administration, server administration and domain administration, to let the administrator sign in to given workstations, servers, and domain controllers based strictly on their job responsibilities.
Standard user account. Grant standard user rights for standard user tasks, such as email, web browsing, and using line-of-business LOB applications.
These accounts should not be granted administrator rights. Ensure that sensitive administrator accounts cannot access email or browse the Internet as described in the following section. To learn more about privileged access, see Privileged Access Devices. It is a best practice to restrict administrators from using sensitive administrator accounts to sign in to lower-trust servers and workstations. This restriction prevents administrators from inadvertently increasing the risk of credential theft by signing in to a lower-trust computer.
Ensure that you either have local access to the domain controller or that you have built at least one dedicated administrative workstation. Restrict domain administrators from having logon access to servers and workstations. Before starting this procedure, identify all OUs in the domain that contain workstations and servers. Any computers in OUs that are not identified will not restrict administrators with sensitive accounts from signing-in to them. Restrict domain administrators from non-domain controller servers and workstations.
Restrict server administrators from signing in to workstations, in addition to domain administrators. For this procedure, do not link accounts to the OU that contain workstations for administrators that perform administration duties only, and do not provide Internet or email access.
You can optionally add any groups that contain server administrators who you want to restrict from signing in to workstations. Completing this step might cause issues with administrator tasks that run as scheduled tasks or services with accounts in the Domain Admins group. The practice of using domain administrator accounts to run services and tasks on workstations creates a significant risk of credential theft attacks and therefore should be replaced with alternative means to run scheduled tasks or services.
Test the functionality of enterprise applications on workstations in the first OU and resolve any issues caused by the new policy. However, do not create a link to the Administrative Workstation OU if it is created for administrative workstations that are dedicated to administration duties only, and that are without Internet or email access.
If you later extend this solution, do not deny logon rights for the Domain Users group. The Domain Users group includes all user accounts in the domain, including Users, Domain Administrators, and Enterprise Administrators. Although user accounts are not marked for delegation by default, accounts in an Active Directory domain can be trusted for delegation.
This means that a service or a computer that is trusted for delegation can impersonate an account that authenticates to them to access other resources across the network. For sensitive accounts, such as those belonging to members of the Administrators, Domain Admins, or Enterprise Admins groups in Active Directory, delegation can present a substantial risk of rights escalation.
For example, if an account in the Domain Admins group is used to sign in to a compromised member server that is trusted for delegation, that server can request access to resources in the context of the Domain Admins account, and escalate the compromise of that member server to a domain compromise.
It is a best practice to configure the user objects for all sensitive accounts in Active Directory by selecting the Account is sensitive and cannot be delegated check box under Account options to prevent these accounts from being delegated.
For more information, see Settings for default local accounts in Active Directory. As with any configuration change, test this enabled setting fully to ensure that it performs correctly before you implement it.
It is a best practice to strictly enforce restrictions on the domain controllers in your environment. This ensures that the domain controllers:. One aspect of securing and managing domain controllers is to ensure that the default local user accounts are fully protected. It is of primary importance to restrict and secure all sensitive domain accounts, as described in the preceding sections. Because domain controllers store credential password hashes of all accounts in the domain, they are high-value targets for malicious users.
When domain controllers are not well managed and secured by using restrictions that are strictly enforced, they can be compromised by malicious users. Follow us for more content. Read more.
