Account options dialog box, numerical values are assigned to the UserAccountControl attribute. The value that is assigned to the attribute tells Windows which options have been enabled.
To view user accounts, click
Start, point to Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
The following table lists possible flags that you can assign. You cannot set some of the values on a user or computer object because these values can be set or reset only by the directory service. Note that Ldp.exe shows the values in hexadecimal. Adsiedit.msc displays the values in decimal. The flags are cumulative. To disable a user's account, set the UserAccountControl attribute to 0x0202 (0x002 + 0x0200). In decimal, this is 514 (2 + 512).
Note You can directly edit Active Directory in both Ldp.exe and Adsiedit.msc. Only experienced administrators should use these tools to edit Active Directory. Both tools are available after you install the Support tools from your original Windows installation media.

Note You cannot assign this permission by directly modifying the UserAccountControl attribute. For information about how to set the permission programmatically, see the "Property flag descriptions" section.
Note In a Windows Server 2003-based domain, LOCK_OUT and PASSWORD_EXPIRED have been replaced with a new attribute called ms-DS-User-Account-Control-Computed. For more information about this new attribute, visit the following Web site:
Property flag descriptions
- SCRIPT - The logon script will be run.
- ACCOUNTDISABLE - The user account is disabled.
- HOMEDIR_REQUIRED - The home folder is required.
- PASSWD_NOTREQD - No password is required.
- PASSWD_CANT_CHANGE - The user cannot change the password. This is a permission on the user's object. For information about how to programmatically set this permission, visit the following Web site:
- ENCRYPTED_TEXT_PASSWORD_ALLOWED - The user can send an encrypted password.
- TEMP_DUPLICATE_ACCOUNT - This is an account for users whose primary account is in another domain. This account provides user access to this domain, but not to any domain that trusts this domain. This is sometimes referred to as a local user account.
- NORMAL_ACCOUNT - This is a default account type that represents a typical user.
- INTERDOMAIN_TRUST_ACCOUNT - This is a permit to trust an account for a system domain that trusts other domains.
- WORKSTATION_TRUST_ACCOUNT - This is a computer account for a computer that is running Microsoft Windows NT 4.0 Workstation, Microsoft Windows NT 4.0 Server, Microsoft Windows 2000 Professional, or Windows 2000 Server and is a member of this domain.
- SERVER_TRUST_ACCOUNT - This is a computer account for a domain controller that is a member of this domain.
- DONT_EXPIRE_PASSWD - Represents the password, which should never expire on the account.
- MNS_LOGON_ACCOUNT - This is an MNS logon account.
- SMARTCARD_REQUIRED - When this flag is set, it forces the user to log on by using a smart card.
- TRUSTED_FOR_DELEGATION - When this flag is set, the service account (the user or computer account) under which a service runs is trusted for Kerberos delegation. Any such service can impersonate a client requesting the service. To enable a service for Kerberos delegation, you must set this flag on the userAccountControl property of the service account.
- NOT_DELEGATED - When this flag is set, the security context of the user is not delegated to a service even if the service account is set as trusted for Kerberos delegation.
- USE_DES_KEY_ONLY - (Windows 2000/Windows Server 2003) Restrict this principal to use only Data Encryption Standard (DES) encryption types for keys.
- DONT_REQUIRE_PREAUTH - (Windows 2000/Windows Server 2003) This account does not require Kerberos pre-authentication for logging on.
- PASSWORD_EXPIRED - (Windows 2000/Windows Server 2003) The user's password has expired.
- TRUSTED_TO_AUTH_FOR_DELEGATION - (Windows 2000/Windows Server 2003) The account is enabled for delegation. This is a security-sensitive setting. Accounts that have this option enabled should be tightly controlled. This setting lets a service that runs under the account assume a client's identity and authenticate as that user to other remote servers on the network.
- PARTIAL_SECRETS_ACCOUNT - (Windows Server 2008/Windows Server 2008 R2) The account is a read-only domain controller (RODC). This is a security-sensitive setting. Removing this setting from an RODC compromises security on that server.
UserAccountControl valuesThese are the default UserAccountControl values for the certain objects:
Domain controller : 0x82000 (532480)
Workstation/server: 0x1000 (4096)
