In Active Directory, default local accounts are used by administrators to manage domain and member servers directly and from dedicated administrative workstations.
Active Directory accounts provide access to network resources. Active Directory User accounts and Computer accounts can represent a physical entity, such as a computer or person, or act as dedicated service accounts for some applications. Each default local account is automatically assigned to a security group that is preconfigured with the appropriate rights and permissions to perform specific tasks.
Active Directory security groups collect user accounts, computer accounts, and other groups into manageable units. For more information, see Active Directory Security Groups. On an Active Directory domain controller, each default local account is referred to as a security principal. A security principal is a directory object that is used to secure and manage Active Directory services that provide access to domain controller resources.
A security principal includes objects such as user accounts, computer accounts, security groups, or the threads or processes that run in the security context of a user or computer account.
For more information, see Security Principals. A security principal is represented by a unique security identifier SID. The SIDs that are related to each of the default local accounts in Active Directory are described in the sections below.
Some of the default local accounts are protected by a background process that periodically checks and applies a specific security descriptor. A security descriptor is a data structure that contains security information that is associated with a protected object. This process ensures that any successful unauthorized attempt to modify the security descriptor on one of the default local accounts or groups is overwritten with the protected settings.
This security descriptor is present on the AdminSDHolder object. 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 to ensure that it is applied consistently.
Be careful when making these modifications, because you are also changing the default settings that are applied to all of your protected accounts. The Administrator account is a default account that is used in all versions of the Windows operating system on every computer and device. The Administrator account is used by the system administrator for tasks that require administrative credentials.
This account cannot be deleted or locked out, but the account can be renamed or disabled. The Administrator account gives the user complete access Full Control permissions of the files, directories, services, and other resources that are on that local server. The Administrator account can be used to create local users, and assign user rights and access control permissions.
Administrator can also be used to take control of local resources at any time simply by changing the user rights and permissions. Although files and directories can be protected from the Administrator account temporarily, the Administrator account can take control of these resources at any time by changing the access permissions. The Administrator account has membership in the default security groups as described in the Administrator account attributes table later in this topic. The security groups ensure that you can control administrator rights without having to change each Administrator account.
In most instances, you do not have to change the basic settings for this account. However, you might have to change its advanced settings, such as membership in particular groups. After installation of the server operating system, your first task is to set up the Administrator account properties securely.
This includes setting up an especially long, strong password, and securing the Remote control and Remote Desktop Services profile settings. The Administrator account can also be disabled when it is not required. Renaming or disabling the Administrator account makes it more difficult for malicious users to try to gain access to the account.
However, even when the Administrator account is disabled, it can still be used to gain access to a domain controller by using safe mode. On a domain controller, the Administrator account becomes the Domain Admin account. The Domain Admin account is used to sign in to the domain controller and this account requires a strong password.
The Domain Admin account gives you access to domain resources. When the domain controller is initially installed, you can sign in and use Server Manager to set up a local Administrator account, with the rights and permissions you want to assign. For example, you can use a local Administrator account to manage the operating system when you first install it.
By using this approach, you can set up the operating system without getting locked out. Generally, you do not need to use the account after installation.
You can only create local user accounts on the domain controller, before Active Directory Domain Services is installed, and not afterwards. When Active Directory is installed on the first domain controller in the domain, the Administrator account is created for Active Directory.
The Administrator account is the most powerful account in the domain. It is given domain-wide access and administrative rights to administer the computer and the domain, and it has the most extensive rights and permissions over the domain. The person who installs Active Directory Domain Services on the computer creates the password for this account during the installation. The Guest account is a default local account that has limited access to the computer and is disabled by default.
By default, the Guest account password is left blank. A blank password allows the Guest account to be accessed without requiring the user to enter a password. The Guest account enables occasional or one-time users, who do not have an individual account on the computer, to sign in to the local server or domain with restricted rights and permissions.
The Guest account can be enabled, and the password can be set up if needed, but only by a member of the Administrator group on the domain. The Guest account has membership in the default security groups that are described in the following Guest account attributes table.
By default, the Guest account is the only member of the default Guests group, which lets a user sign in to a server, and the Domain Guests global group, which lets a user sign in to a domain.
A member of the Administrators group or Domain Admins group can set up a user with a Guest account on one or more computers. Because the Guest account can provide anonymous access, it is a security risk. It also has a well-known SID. For this reason, it is a best practice to leave the Guest account disabled, unless its use is required and then only with restricted rights and permissions for a very limited period of time.
When the Guest account is required, an Administrator on the domain controller is required to enable the Guest account. The Guest account can be enabled without requiring a password, or it can be enabled with a strong password. The Administrator also grants restricted rights and permissions for the Guest account. To help prevent unauthorized access:. Do not grant the Guest account the Shut down the system user right. When a computer is shutting down or starting up, it is possible that a Guest user or anyone with local access, such as a malicious user, could gain unauthorized access to the computer.
Do not provide the Guest account with the ability to view the event logs. 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 undertaken.
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 process is similar to creating a preconfigured user profile except that the resulting profile is made available to multiple users. Create a profile using the steps outlined above. After copying the profile to the network, you must configure the profile path for the users to whom the profile will apply. Windows Server simplifies this task, in that you can multiselect users and change the profile path for all users simultaneously. The profile path is configured as a property of one or more user objects.
It is not assigned to a group object. Although the concept is that of a group profile, do not fall into the trap of associating the profile with a group object itself. Finally, because more than one user will be accessing a group profile, you must make a group profile mandatory, as described in the following section. More specifically, a mandatory profile does not maintain changes between sessions.
Therefore, although a user can make changes, the next time the user logs on, the desktop will look the same as the last time he or she logged on. Changes do not persist. Mandatory profiles can be helpful in situations in which you want to lock down the desktop.
To configure a profile as mandatory, simply rename a file in the root folder of the profile. Interestingly, mandatory profiles are not configured through the application of permissions.
The file you need to rename is Ntuser. You may also need to configure Windows Explorer to display file extensions. Locate the Ntuser. Rename the file to Ntuser. The profile, whether roaming or local, is now mandatory. Settings include: Shortcuts in your Start menu, on your desktop, and in your Quick Launch bar Documents on your desktop and, unless redirection is configured, in your My Documents folder Tip The properties of the My Documents folder, and the Folder Redirection policies in group policy, enable you to redirect My Documents so that it targets a network folder.
Note Be sure to configure share permissions allowing Everyone Full Control. Note You must be a member of the Administrators group to copy a profile. Tip Be careful with preconfigured roaming profiles, or any roaming profiles, to pay attention to potential issues related to different hardware on systems to which a user logs on. Tip The profile path is configured as a property of one or more user objects. Windows Server : Managing User Profiles. User Profiles A user profile is a collection of folders and data files that contain the elements of your desktop environment that make it uniquely yours.
