3236
3237 usri11_logon_server points to a null terminated ASCII string that

3247 There may be up to 8 workstations, with the names separated by

3254 usri11_units_per_week specifies the equal number of time units into
3255 which a week is divided. This value must be equal to 168.
3256
3257 usri11_logon_hours points to a 21 byte (168 bits) string that
3258 specifies the time during which the user can log on. Each bit
3259 represents one unique hour in a week. The first bit (bit 0, word
