pbeckford,
I'm sorry...the person that asked me to post this for them has gone on vacation and will not be back until 9/22. I will follow-up with them on 9/22 and post a reply.
Thanks.
Hello,
We recently installed, within the past 2 weeks, Microsoft's CA on one of our domain member servers. Now we are seeing that users (about 30 so far)are getting issued certs for BASIC EFS (Encrypting File System). So my questions are:
1. Is this happening by design?
2. I've searched some of the PCs for ecrypted files but, most don't have any that I can find. Only 1 PC so far out of the entire list has some files that are encrypted. If the PCs don't have any encrypted files then why did they need the cert in the first place?
3. If the users are NOT knowingly encrypting the files, then what is doing it?
I have disabled the CA service as requested by my manager until we understand this better.
4. Were the users able to encrypt files prior to the installation of the CA?
Any help is greatly appreciated! Thanks!

I ran into this as well with users automatically obtaining certificates when encrypting files. You can change this by changing permissions on the certificate template but before you allow anyone to start encrypting files, I believe you need to ensure you have setup an EFS recovery agent before you get burned. If a user loses their key, which is stored in their profile, their encrypted data would be lost without a recovery agent or backup of their key. The following is a pretty good artical on setting up EFS:
