When deploying agents using an MST file, the agent does not appear in the Agent Management page or you receive a certificate error

Updated Aug 24, 2016

Overview

 

When mass-deploying agents using an MST file, you may receive a certificate error or the agents do not register with the Orion server.

When the agents do not register, the agents do not appear in the Agent Management page.

Environment

  • NPM 11.5 or later
  • Agent version 1.5 or later

 

Cause 

This is caused by mismatched security certificates.

  2. Log on to the computer running your primary Orion server.
  3. Open the Orion Database Manager.
  4. Execute the following query:
    DELETE FROM [AgentManagement_Pkcs12Certificates] WHERE [CertificateType] = 2
  5. Open the personal certificate store for the local computer.
