If you should forget your Trend Micro server console password, you can reset  it by doing the following.
 
 

1. Navigate to: \Program Files\Trend Micro\security server(officescan)\private
2. Open ofcserver.ini in Notepad
3. Press CTRL-F to search for: master_pwd
4. Once found, the string should look similar to: master_pwd=!CRYPT!xxxxx
5. xxxxx is representative of a long string of hex characters making up an encrypted password
6. In place of !CRYPT!xxxxx put “70″ so it will look like: master_pwd=70
7. 70 is the hexadecimal value for “1″
8. Save the file
9. Press Start -> Run -> Type: services.msc and press enter
10. Find “Trend Micro Security Server Master Service” and restart the service
11. Login to the Trend Micro Security Dashboard with the password as “1″ without the quotations
12. The default URL for the dashboard is: https://IPADDRESS:4343/officescan/default_SMB.htm
