We have an Old Windows 2008 R2 VM that has a CA installed on it.
It has been giving out <domain>\<Machine>$ and <domain>\<User> Certs.
Nothing else on the Machine. I've never been a Fan of Upgrading Servers vs Fresh installs. There are no Certs on here besides the ones that it gave to the PCs and Users. No Special Templates or anything. I May have used it for an Exchange Server, though have a Wildcard Cert for that now.
What is best to replace this CA. Do I need to replace it?
