Members
usri2_name
Type: LPWSTR
A pointer to a Unicode string that specifies the name of the user account. Calls to the NetUserSetInfo function ignore this member. For more information, see the following Remarks section.
usri2_password
Type: LPWSTR
A pointer to a Unicode string that specifies the password for the user identified by the usri2_name member. The length cannot exceed PWLEN bytes. The NetUserEnum and NetUserGetInfo functions return a NULL pointer to maintain password security.
By convention, the length of passwords is limited to LM20_PWLEN characters.
usri2_password_age
Type: DWORD
The number of seconds that have elapsed since the usri2_password member was last changed. The NetUserAdd and NetUserSetInfo functions ignore this member.
usri2_priv
Type: DWORD
The level of privilege assigned to the usri2_name member. For calls to the NetUserAdd function, this member must be USER_PRIV_USER. For the NetUserSetInfo function, this member must be the value returned by the NetUserGetInfo function or the NetUserEnum function. This member can be one of the following values. For more information about user and group account rights, see Privileges.
| Value | Meaning |
|---|---|
|
Guest |
|
User |
|
Administrator |
usri2_home_dir
Type: LPWSTR
A pointer to a Unicode string specifying the path of the home directory for the user specified by the usri2_name member. The string can be NULL.
usri2_comment
Type: LPWSTR
A pointer to a Unicode string that contains a comment to associate with the user account. The string can be a NULL string, or it can have any number of characters before the terminating null character.
usri2_flags
Type: DWORD
This member can be one or more of the following values.
Note that setting user account control flags may require certain privileges and control access rights. For more information, see the Remarks section of the NetUserSetInfo function.
| Value | Meaning |
|---|---|
|
The logon script executed. This value must be set. |
|
The user's account is disabled. |
|
The home directory is required. This value is ignored. |
|
No password is required. |
|
The user cannot change the password. |
|
The account is currently locked out. You can call the NetUserSetInfo function to clear this value and unlock a previously locked account. You cannot use this value to lock a previously unlocked account. |
|
The password should never expire on the account. |
|
The user's password is stored under reversible encryption in the Active Directory. |
|
Marks the account as "sensitive"; other users cannot act as delegates of this user account. |
|
Requires the user to log on to the user account with a smart card. |
|
Restrict this principal to use only Data Encryption Standard (DES) encryption types for keys. |
|
This account does not require Kerberos preauthentication for logon. |
|
The account is enabled for delegation. This is a security-sensitive setting; accounts with this option enabled should be tightly controlled. This setting allows a service running under the account to assume a client's identity and authenticate as that user to other remote servers on the network. |
|
The user's password has expired.
Windows 2000: This value is not supported. |
|
The account is trusted to authenticate a user outside of the Kerberos security package and delegate that user through constrained delegation. This is a security-sensitive setting; accounts with this option enabled should be tightly controlled. This setting allows a service running under the account to assert a client's identity and authenticate as that user to specifically configured services on the network.
Windows XP/2000: This value is not supported. |
The following values describe the account type. Only one value can be set. You cannot change the account type using the NetUserSetInfo function.
usri2_script_path
Type: LPWSTR
A pointer to a Unicode string specifying the path for the user's logon script file. The script file can be a .CMD file, an .EXE file, or a .BAT file. The string can also be NULL.
usri2_auth_flags
Type: DWORD
The user's operator privileges.
Calls to the NetUserGetInfo and NetUserEnum functions return a value based on the user's local group membership. If the user is a member of Print Operators, AF_OP_PRINT is set. If the user is a member of Server Operators, AF_OP_SERVER is set. If the user is a member of the Account Operators, AF_OP_ACCOUNTS is set. AF_OP_COMM is never set. For more information about user and group account rights, see Privileges.
The following restrictions apply:
- When you call the NetUserAdd function, this member must be zero.
- When you call the NetUserSetInfo function, this member must be the value returned from a call to NetUserGetInfo or to NetUserEnum.
usri2_full_name
Type: LPWSTR
A pointer to a Unicode string that contains the full name of the user. This string can be a NULL string, or it can have any number of characters before the terminating null character.
usri2_usr_comment
Type: LPWSTR
A pointer to a Unicode string that contains a user comment. This string can be a NULL string, or it can have any number of characters before the terminating null character.
usri2_parms
Type: LPWSTR
A pointer to a Unicode string that is reserved for use by applications. This string can be a NULL string, or it can have any number of characters before the terminating null character. Microsoft products use this member to store user configuration information. Do not modify this information.
usri2_workstations
Type: LPWSTR
Important
You should no longer use usri2_workstations. Instead, you can control sign-in access to workstations by configuring the User Rights Assignment settings (Allow log on locally and Deny log on locally, or Allow log on through Remote Desktop Services and Deny log on through Remote Desktop Services).
A pointer to a Unicode string that contains the names of workstations from which the user can log on. As many as eight workstations can be specified; the names must be separated by commas. A NULL string indicates that there is no restriction. To disable logons from all workstations to this account, set the UF_ACCOUNTDISABLE value in the usri2_flags member.
usri2_last_logon
Type: DWORD
The date and time when the last logon occurred. This value is stored as the number of seconds that have elapsed since 00:00:00, January 1, 1970, GMT. This member is ignored by the NetUserAdd and NetUserSetInfo functions.
This member is maintained separately on each backup domain controller (BDC) in the domain. To obtain an accurate value, you must query each BDC in the domain. The last logon occurred at the time indicated by the largest retrieved value.
usri2_last_logoff
Type: DWORD
This member is currently not used.
Indicates when the last logoff occurred. This value is stored as the number of seconds that have elapsed since 00:00:00, January 1, 1970, GMT. A value of zero indicates that the last logoff time is unknown.
This member is maintained separately on each backup domain controller (BDC) in the domain. To obtain an accurate value, you must query each BDC in the domain. The last logoff occurred at the time indicated by the largest retrieved value.
usri2_acct_expires
Type: DWORD
The date and time when the account expires. This value is stored as the number of seconds elapsed since 00:00:00, January 1, 1970, GMT. A value of TIMEQ_FOREVER indicates that the account never expires.
usri2_max_storage
Type: DWORD
The maximum amount of disk space the user can use. Specify USER_MAXSTORAGE_UNLIMITED to use all available disk space.
usri2_units_per_week
Type: DWORD
The number of equal-length time units into which the week is divided. This value is required to compute the length of the bit string in the usri2_logon_hours member.
This value must be UNITS_PER_WEEK for LAN Manager 2.0. This element is ignored by the NetUserAdd and NetUserSetInfo functions.
For service applications, the units must be one of the following values: SAM_DAYS_PER_WEEK, SAM_HOURS_PER_WEEK, or SAM_MINUTES_PER_WEEK.
usri2_logon_hours
Type: PBYTE
A pointer to a 21-byte (168 bits) bit string that specifies the times during which the user can log on. Each bit represents a unique hour in the week, in Greenwich Mean Time (GMT).
The first bit (bit 0, word 0) is Sunday, 0:00 to 0:59; the second bit (bit 1, word 0) is Sunday, 1:00 to 1:59; and so on. Note that bit 0 in word 0 represents Sunday from 0:00 to 0:59 only if you are in the GMT time zone. In all other cases you must adjust the bits according to your time zone offset (for example, GMT minus 8 hours for Pacific Standard Time).
Specify a NULL pointer in this member when calling the NetUserAdd function to indicate no time restriction. Specify a NULL pointer when calling the NetUserSetInfo function to indicate that no change is to be made to the times during which the user can log on.
usri2_bad_pw_count
Type: DWORD
The number of times the user tried to log on to the account using an incorrect password. A value of – 1 indicates that the value is unknown. Calls to the NetUserAdd and NetUserSetInfo functions ignore this member.
This member is replicated from the primary domain controller (PDC); it is also maintained on each backup domain controller (BDC) in the domain. To obtain an accurate value, you must query each BDC in the domain. The number of times the user tried to log on using an incorrect password is the largest value retrieved.
usri2_num_logons
Type: DWORD
The number of times the user logged on successfully to this account. A value of – 1 indicates that the value is unknown. Calls to the NetUserAdd and NetUserSetInfo functions ignore this member.
This member is maintained separately on each backup domain controller (BDC) in the domain. To obtain an accurate value, you must query each BDC in the domain. The number of times the user logged on successfully is the sum of the retrieved values.
usri2_logon_server
Type: LPWSTR
A pointer to a Unicode string that contains the name of the server to which logon requests are sent. Server names should be preceded by two backslashes (\). To indicate that the logon request can be handled by any logon server, specify an asterisk (\*) for the server name. A NULL string indicates that requests should be sent to the domain controller.
For Windows servers, NetUserGetInfo and NetUserEnum return \*. The NetUserAdd and NetUserSetInfo functions ignore this member.
usri2_country_code
Type: DWORD
The country/region code for the user's language of choice.
usri2_code_page
Type: DWORD
The code page for the user's language of choice.
Remarks
