I'm totally new to Installing and using CA. My predessor left me with a mess. So here's what I'm seeing. I'm trying to clean up a CA mess. When I look at the Enterprise PKI it shows it's showing an error on 2 CA's that both show errors. The first on the list doesn't have Certificate authority installed, the one directly after has it enabled but the CA Certificate shows as "Not Time Valid" and the AIA location #1 as unable to download.
Looking at the issued certificates most have expired.
Where do I start?
Any help would be appreciatted.
