Symantec Endpoint Protection Manager console logon authentication

Symantec Endpoint Protection Manager Console logon authentication fail, Even after executing resetpass.bat

Have you tried to change the admin account in the manager console to something else?
if you did then try to apply the resetpass.bat without changing the account name.

If that didn't work then try changing the value in the following reg..
HKLM\SOFTWARE\INTEL\LANDesk\VirusProtect6\CurrentVersion\ConsolePassword
to value 1084A085DC6BD2D755D4D6A7726

This will reset the password to Symantec.

As well if that didn't work Try looking for a file name called "Iforgot.exe" then double click to reset the password.

good luck.
