Knowledge Base article:

Summary

The certificate use for authentication is about to expire. This certificate is used for certificate based authentication from this HealthService to other HealthServices.

This is the same certificate that was imported using the MOMCertImport.exe utility.

Once the certificate expires, the agent or management server will not be able to communicate with or report data to the management group.

Causes

The certificate is about to expire. After it has expired, the HealthService will be unable to authenticate to other HealthServices.

Resolutions

Obtain a new certificate and import it using the MOMCertImport.exe utility.
