We don't really use this anyway, although some people did, in the past. I
have to decomission the hardware on which the CA lives and for the near-term,
have decided to just not establish another.
I have a couple of questions: First of all, if somebody, somewhere, has an
encrypted folder (they all swear they don't, but I can't go poking around to
make sure), will they lose access to their files or will their files simply
become unencrypted when I decomission the CA?
Secondly, when I look at issued certificates, I see some of my server - most
notably, my DCs. I don't know exactly why they've requested certificates,
but what will happen to them if I decomission the CA?

Thanks for any advice!
Mark

If decommissions, and you have not maintained the KRA certificate and
private key or the DRA certificate and private key, they are out of luck.
Decommissioning a CA does not decrypt files.

They will fail for LDAP/SSL connections. You should remove all of the DC
certs
certutil -dcinfo DELETEALL

Okay, then is there a way I can test this? For instance, can I stop a CA
service on the server to "simulate" removal of the CA? Something that I can
test and then if somebody screams (unlikely, but you never know), I can just
turn it back on and dig in further to help them get their stuff unencrypted?

Running this on the CA will remove them and I'll be okay?

Thanks for the help,
Mark

ANd yes, you can run the command from the CA.
If there are multiple domains, the command must be run on one domain member
(does not have to be a CA) as a member of that domain for each domain
