Thanks everyone for all your input. To recap; the Symantec Endpoint Protection Manager Service will not start, the problem that Technical Support found was with tomcat, when I was instructed to run the Configuration Wizard I couldn't run it because I don't remember the DBA password.
Now, I checked one of the links that were suggested, but I've already tried to check using the ODBC method with no luck. Of what I can gather here, I will have to reinstall SEPM and perform disaster recovery without database password. I haven't try that yet and it looks that I would not try that for a couple of days since we are working with our contingency plan due to the proximity of Tropical Depression Nine on the Caribbean.
Thanks again to all for your input, I'll get back to you with the results from the disaster recovery.
