You need to change the password for your account or another administrator's account if the password is forgotten, lost, or compromised.
The following rules apply to changing passwords:
System administrators can change the password for all administrators.
Domain administrators can change the password for other domain administrators and limited administrators within the same domain.
Limited administrators can change their own passwords only.
If you change the password to fix an administrator account lockout, the administrator must still wait for the lockout period to expire.
To change the password for an administrator account
In the console, click Admin > Administrators.
Under Administrators, select the administrator account, and then click Change password.
Press F1 to see the password restrictions.
Type both your password and the administrator's new password.
When you configure the management server and select the embedded database, the password you enter for the default administrator account, admin, also becomes the database password. If you change the default administrator's password, the database password does not change automatically. As of 14, you can change the database password by rerunning the Management Server Configuration Wizard and reconfiguring Symantec Endpoint Protection Manager.
To change the embedded database password
On the Windows Start menu, navigate to Symantec Endpoint Protection Manager > Symantec Endpoint Protection Manager Tools > Management Server Configuration Wizard.
Click Reconfigure the management server, and then click Next > Next.
Click Default Embedded database > Change the database administrator password, and type the new password.
Follow the instructions in each panel to finish the configuration
