Strange behavior AD FS Windows Server 2012 R2 after changing the service communications certificate

Yesterday I ran into a problem in my demo environment after I changed the AD FS service communications certificate. My old certificate wasn’t prepared for DRS (Device Registration Service) and since I wanted to test some things with DRS in combination with Office 365 I needed to replace the certificate with a new one which included the enterpriseregistration.domain.com UPN suffix.
