UserAccountControl 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.
