Recently, we moved Active Directory Certificate Services off of our exchange server and onto a dedicated ADCS box. We kept the same CA name, however the server name changed. After migrating the database and configuration from the old server to the new one, we are now getting the status 'Revocation check failed' with our exchange certificates. We are on Server 2012 R2 with Exchange 2013.
PKIView.msc:
CA Certificate = OK
AIA Location #1 = OK
CDP Location #1 = OK
DeltaCRL Location #1 = OK
