In rare circumstances, it may fail to reset a Deep Security Agent (DSA) using either of the following methods:

  • Deactivate the DSA on the Deep Security Manager (DSM) console.
  • Run "dsa_control -r, /r, --reset" on the command line.

To force reset the DSA:

Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.
  1. Boot the machine into Safe Mode.
  2. Set the following services to start manually:
    • Trend Micro Deep Security Agent
    • Trend Micro Solution Platform
  3. Disable the Self-Protection of DSA by setting the value of the following registry key hive to "0"

    Hkey_Local_Machine\Software\TrendMicro\Deep Security Agent\Self Protect=0

  4. Rename the following files under Deep Security Agent directory:
    • config.bin
    • ds_agent.config
  5. Boot the machine in Normal Mode.
  6. Start the Trend Micro Deep Security Agent service.
  7. Run the following command to reset the agent:

    dsa_control.exe -r

Optionally, you can uninstall the DSA using the Control Panel's Add/Remove Programs option. If the process fails please uninstall using the steps detailed on this KB article.
