Certificate Load Warning

Microsoft.ActiveDirectoryFederationServices20.FederationServerAdditionalCertificateLoadWarningMonitor (UnitMonitor)

Knowledge Base article:

Summary

This monitor indicates that the certificate could not be found in the Local Computer Personal certificate store. If the same problem does not occur again within 15 minutes, the health state of this monitor will change back to a Green state. A corresponding alert is generated by the alert rule, and it must be resolved manually.

Causes

The specified certificate either does not exist in the local certificate store, or the AD FS service account does not have permissions to access the certificate.

Resolutions

Ensure that the certificate (identified by its thumbprint in the event text) has been added to the LocalMachine\My store folder on the federation server computer. Also, verify that the AD FS service account has access to the private key for this certificate. For more information, see "Things to Check Before Troubleshooting AD FS" section in the AD FS troubleshooting guide.
