Hi,
SymcorpUI.exe shows SEP client GUI version.
If you cannot recover your administrator password with the functionality, Symantec cannot assist with the recovery of your password. You must perform disaster recovery to rebuild Symantec Endpoint Protection Manager. Therefore, it is critical that you configure your email settings correctly when you set up the management server and when you audit administrator account information.
In versions 12.1 RU1 (12.1.1) and earlier, you can use the ResetPass.bat
script, found in the /Symantec Endpoint Protection Manager/Tools
installation folder. This script forcefully resets the default administrator account password to admin
if it is not linked to an Active Directory account.
Symantec no longer supports the script. In versions 12.1 RU1 MP1 (12.1.1.1) and later, the script has not been tested and may cause damage to Symantec Endpoint Protection Manager or the database.
