Hey everyone! I'm reaching out for some assistance regarding our internal Certificate Authority (CA). We migrated from a 2012 server to a 2022 server last year, and everything was running smoothly until this past week. We've recently encountered some issues: our Windows PIN functionality has stopped working, and Forticlient EMS is having domain sync and certificate problems. When I checked the domain controllers, I found some expired certificates from last week. I attempted to renew one of them, but the templates appeared unavailable or grayed out. Upon launching the CA utility on the CA server, I encountered an error that stated, 'Template information could not be loaded' with 'Element not found.' I saw some suggestions online about renewing the CA certificate directly, but I'm wary of potential repercussions. Any tips or guidance would be greatly appreciated!

It looks like your issue with the templates might be related to a firewall blocking communication between the CA and your domain controllers. That's a good first place to check. Templates are stored in Active Directory, so ensure that there's nothing preventing the CA server from accessing this information. If you can verify connectivity, that’ll help narrow down the problem.
I'd suggest starting with the PKI View tool to get an overview of your environment's health. It can provide valuable insights into what might be going wrong. Also, run the command 'certutil -ping' which will help confirm connectivity to your AD. From what you've described, if you've already checked that and found everything else as expected, you might want to look into renewing your CA certificate and redistributing it across all domain controllers. This could help resolve some of the issues you're facing. Good luck!
