Hi Tangsuan,

Following is the documented procedure for password recovery..

In order to modify the GUI root user password, you will need to login to the NCS CLI

as an admin user, and enter the command

"ncs password root password <new password>" (without the quotes)

This should set the web interface root user password :

If you have lost your CLI password , try the default logging that is  ,

CLI user is admin and not root, so please try logging in as admin with

the password that was set during setup. If that does not work , you need

the install disk that came with the appliance to recover that password.

Follow these steps:
