This is because a Windows account unlisted in the built-in Administrators group was used to connect with the SQL database when the TMCM server was installed.

Trend Micro Control Manager and Trend Micro Management Infrastructure services used that account in starting the TMCM console, causing the error.

To resolve this issue:

  1. Add the account used by the Trend Micro Control Manager service to the built-in Administrators group of your TMCM machine.
  2. Restart the Trend Micro Control Manager and Trend Micro Management Infrastructure services.
