Summary

When a computer has an issue with certificate verification, it cannot receive policy and cannot be removed due to self-protection.

Running the command "dsa_control" shows the following error message:

c:\Program Files\Trend Micro\Deep Security Agent>dsa_control -r   Unable to load agent certificate for verification.   Path is: C:\ProgramData\Trend Micro\Deep Security Agent\dsa_core\ds_agent.crt   Error is: error:02001005:system library:fopen:Input/output error [fopen('C:\Prog   ramData\Trend Micro\Deep Security Agent\dsa_core\ds_agent.crt','r')]   sslCtx:UseCredentials() failed - error:2006D002:BIO routines:BIO_new_file:system   lib []

The issue happens due to any of the following reasons:

  • A non-administrator account is used to perform the command and it has no permission to read the file.
  • The certificate file is corrupted.

To resolve the issue, do the following using an administrator's account:

  1. Stop the Deep Security Agent service.
  2. Delete the file C:\ProgramData\Trend Micro\Deep Security Agent\dsa_core\ds_agent.crt.
  3. Start the Deep Security Agent service.
  4. Verify that a new file ds_agent.crt is generated after restarting the agent service.
  5. Run the command "dsa_control" again.
