Cannot enable local authentication and/or reset password

Cannot enable local authentication and/or reset password

Hi,
Interesting issue... my DC is down and i can't log in into ServiceDesk Plus locally.
Yes, i've tried all solutions listed her on the forum including this command:

 update globalconfig set paramvalue='true' where parameter='Enable_LocalAuthentication_Login';
It shows UPDATE 1 as it was successful, i restart the service, no luck.

I tried script - it did not work, throw's up an error:
Error: Could not find or load main class com.manageengine.servicedesk.reset.util.ResetPasswordUtil

no joy.
So in fact i'm at loss now - how to get into the program.
Does anyone else have any similar issue?
