If none of the administrators can log to the Management Client because of account-related issues, you can create an emergency administrator account.
Steps
-
On the command line of the Management Server computer, stop the Management Server service.
-
Create an account with unrestricted permissions using the sgCreateAdmin script (located in the <installation directory>/bin folder).
Note: If you installed the Management Server in the C:\Program Files\Forcepoint\SMC directory in Windows, some program data might be stored in the C:\ProgramData\Forcepoint\SMC directory.
Result
You can now log on to the Management Client using this account, change passwords, and create new accounts normally.
