The replication of certificates from the central management store to the local machine failed due to a problem assigning the certificate to the services running on the local machine. Skype for Business Server 2015, Replica Replicator Agent will continuously attempt to retry the replication. While this condition persists, the certificates on the local machine will not be updated.
The service running on the local machine is not configured correctly or cannot use the certificate.
Ensure that local services are properly setup. Run Enable-CSComputer Power Shell command on the local machine to validate the configuration.
