如果丢失 admin 密码，则可以使用下列步骤将安全设备重置到其缺省设置。配置 将失去，但是对设备的访问将恢复。要执行此操作，需要连接控制台。

注意: 在缺省情况下，会启用设备恢复功能。可通过输入 unset admin device-reset 命 令禁用它。同样，如果安全设备处于 FIPS 模式，恢复特征被自动禁用。

1. 在登录提示下，输入设备的序列号。

2. 在密码提示下，再次输入序列号。

出现以下消息:

!!!! Lost Password Reset !!!!You have initiated a command to reset the device to 
factory defaults, clearing all current configuration, keys and settings.Would 
you like to continue? y/n

3. 按 y 键。

出现以下消息:

!! Reconfirm Lost Password Reset !!If you continue, the entire configuration of 
the device will be erased.In addition, a permanent counter will be incremented 
to signify that this device has been reset.This is your last chance to cancel 
this command.If you proceed, the device will return to factory default 
configuration, which is: System IP: 192.168.1.1; username: netscreen; 
password: netscreen.Would you like to continue? y/n

4. 按 y 键，重置设备。现在可以用 netscreen 作为缺省用户名和密码进行登录。
