Title
How to recover a non-accessible Email Security appliance and also reset the admin password
Resolution

Problem Definition:

An Email Security appliance can be considered non-accessible when the following is true:

1. No Ping possible

2. No port 22 access

If this is the case, the email security will usually stop processing emails (because it is not available over the network) and the customer cannot log on to the Web-interface to investigate. This guide will also explain how to reset the local admin credentials to “admin”/”password”.

The Web-Interface is only available over the network and cannot be accessed with the Monitor and Keyboard connected to it directly.

Resolution :

To recover from this position, you will need to connect a monitor and keyboard directly to the appliance. This will allow you to verify that you are using a correct IP configuration and also to access the Sonicwall Command Line Interface if this becomes necessary.

1. Connect keyboard and monitor to ES
2. Restart
3. Keep pressing the "tab" button while it restarts. After a few moments, you will see the “Grub Loader Menu” like below:
