Let's start this with a disclaimer: I'm a complete noob in AD. I need an AD to test something else and I've followed step by step the configuration in this guide: https://mjcb.io/blog/2020/03/09/certificate-authority-windows-server-2019-part-4/
Everything was going very smoothly until I reached "4.7 Verify OCSP Status" and the status of the Enterprise PKI Console was "Error". I've tried to fix it by revoking the CA Exchange Certificate (and maybe something else, I can't remember!) but somehow I think I made the problem even worse (see image attached).
Can you please help me out? Many thanks in advance!
