3355 00:00:00, January 1, 1970.
3356
3357 usri11_last_logoff specifies the time when the user last logged off.
3358 This value is stored as the number of seconds elapsed since
3359 00:00:00, January 1, 1970. A value of 0 means the last logoff
3360 time is unknown.
3361
3362 usri11_bad_pw_count specifies the number of incorrect passwords
3363 entered since the last successful logon.
3364
3365 usri11_log1_num_logons specifies the number of times this user has
3366 logged on. A value of -1 means the number of logons is unknown.
3367
3368 usri11_logon_server points to a null terminated ASCII string that
3369 contains the name of the server to which logon requests are sent.
3370 A null string indicates logon requests should be sent to the
3371 domain controller.
3372
3373 usri11_country_code specifies the country code for the user's language
3374 of choice.
3375
3376 usri11_workstations points to a null terminated ASCII string that
3377 contains the names of workstations the user may log on from.
3378 There may be up to 8 workstations, with the names separated by
3379 commas. A null strings indicates there are no restrictions.
3380
3381 usri11_max_storage specifies the maximum amount of disk space the user
3382 can occupy. A value of 0xffffffff indicates there are no
3383 restrictions.
3384
3385 usri11_units_per_week specifies the equal number of time units into
3386 which a week is divided. This value must be equal to 168.
3387
3388 usri11_logon_hours points to a 21 byte (168 bits) string that
3389 specifies the time during which the user can log on. Each bit
3390 represents one unique hour in a week. The first bit (bit 0, word
3391 0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is

3402 Sunday, 1:00 to 1:59 and so on. A null pointer indicates there
3403 are no restrictions.
3404
3405 usri11_code_page specifies the code page for the user's language of
3406 choice
3407
3408 All of the pointers in this data structure need to be treated
3409 specially. The pointer is a 32 bit pointer. The higher 16 bits need
3410 to be ignored. The converter word returned in the parameters section
3411 needs to be subtracted from the lower 16 bits to calculate an offset
3412 into the return buffer where this ASCII string resides.
3413
3414 There is no auxiliary data in the response.
