[ScreenOS] Console message - 'Your license key content is invalid'



Article ID: KB25599 KB Last Updated: 20 Aug 2012Version: 1.0
This article describes the issue of the Your license key content is invalid error message being generated in the console, whenever the device is rebooted.
When the firewall is rebooted, the console displays the following error message:

What is the meaning of this error message and its impact?
  • This message is peculiar to NS-5000 firewalls and is unrelated to any license key(s) on the firewall (Advanced, Vsys, Zone, and so on).

  • The error message is generated when the license.key file, which is stored in the flash, is corrupted.

  • This file is created with a specific combination of chassis and modules and when the combination is changed, serial numbers will not match; which results in file corruption. The file has to be removed.
To resolve this issue, remove the corrupted license.key file from flash. Use the following command and reboot the device:
firewall -> delete file /license.key
This will remove the corrupted file from flash. If any licenses (Advanced, Vsys, Zone, and so on) are present, they will be automatically removed:
firewall -> get lic

The licenses should be re-installed, when the device is up. After re-installing the licenses, the license.key file will re-appear in the flash:
