Windows use requests and responses to enroll for a certificate from a certification authority (CA). The process can get interrupted by a series of problems. Hence, it can result in the Event ID 86: CertificateServicesClient-CertEnroll in Windows.

Likewise, users complain about running into the Event ID 41 error on Windows 11.

What is Event ID 86?

The Event ID 86 is a process in the Windows event log that provides an in-depth record of events concerning the system. It indicates the Active Directory Certificate Services can’t use the provider stated in the registry for encryption keys.

Furthermore, Event ID 86 is logged into the Event Log by the Certificate Services Client and contains the details about the certificate request.

However, the Event ID 86: CertificateServicesClient-CertEnroll in Windows 10 can occur for many reasons. Some are:

  • Issues with the certificate request or the Certificate Authority – If the Active Directory Certificate Services on your PC are faulty or not intact, it can cause its processes to run into issues.
  • Windows Updates or Drivers issues – Windows PCs can malfunction with their processes if a corrupt update is installed or a pending update is not installed. Likewise, outdated drivers on the PC may result in errors.
  • BIOS-related concerns – You can encounter the Event ID 86 on Windows 10 if you don’t have the latest BIOS installed on your PC. Likewise, other issues with the BIOS can affect the certificate processes on your PC.

Other factors can be responsible for the Event ID 86 on your PC. Nonetheless, you can fix it by troubleshooting your computer.
