| DWORD level, | |
| LPBYTE buf, | |
| LPDWORD parm_err | |
| ); |
Parameters

| 1 | The buf parameter points to a USER_INFO_1 structure. |
| 2 | The buf parameter points to a USER_INFO_2 structure. |
| 3 | The buf parameter points to a USER_INFO_3 structure. |
buf
Pointer to the buffer in which the data set with the level parameter is stored.
parm_err
Optional pointer to a DWORD that contains the index of the first parameter that causes ERROR_INVALID_PARAMETER. If NULL, the parameter is not returned on error.
Return Values

If the function fails, the return value is one of the following error codes.
| Value | Meaning |
| ERROR_ACCESS_DENIED | The user does not have access to the requested information. |
| NERR_InvalidComputer | Thiecomputer name is invalid. |
| NERR_NotPrimary | The operation is allowed only on the primary domain controller of the domain. |

| NERR_UserExists | The user account already exists. |

Remarks
Server users must use a system in which the server creates a WINDOWS NT system account for the new user. The creation of this account is controlled by several parameters in the server's LANMAN.INI file.
If the newly added server user name already exists as a Windows NT system user, the useril_home_dir member of the USER_INFO_1 structure is ignored. The NetUserAdd function supports USER_INFO_1 and USER_INFO_2 structures. Using members of USER_INFO_1 initializes default values in USER_INFO_2 and USER_INFO_3 structures.
Subsequent NetUserSetInfo calls can change the default values. The following are possible default values.
| Member | Default Value |
| usriX_auth_flags | None (0) |
| usriX_full_name | usri1_name |
| usriX_usr_comment | None (null string) |
| usriX_parms | None (null string) |
| usriX_workstations | All (null string) |
| usriX_acct_expires | Never (TIMEQ_FOREVER) |
| usriX_max_storage | Unlimited (USER_MAXSTORAGE_UNLIMITED) |
| usriX_logon_hours | Logon allowed at any time (each element 0xFF; all bits set to 1) |
| usriX_logon_server | Any domain controller (\\*) |
| usriX_country_code | Current (country_code on the server |
