Modifying the Communicator Heartbeat Protocol

By default, the connectionless User Datagram Protocol (UDP) is used to send Communicator Heartbeat from managed product to the Control Manager server.

  1. Open <root>:\program files\Trend Micro\COMMON\TMI\TMI.cfg using any text editor (for example, Notepad).

    Making incorrect changes to the configuration file can cause serious system problem. Back up TMI.cfg to restore your original settings.

  2. Change the value of AllowUDP parameter to 0.
  3. Save and close TMI.cfg.
  4. Open the Windows Services screen to stop and then restart the Control Manager services.
  5. Repeat steps 1 to 3 to modify TMI.cfg for all agents present in your Control Manager network.

    Set all TMI.cfg in your Control Manager network (server and agents) to the same security level value (AllowUDP). Otherwise, the server and agent communication will not work.
