If you attended any of the launch events held across Canada in the last month or so, you may have seen the session we presented on security in which we talked a little about a new feature in Vista called BitLocker. One common question was wether or not AD could be configured to store BitLocker keys with a users account in AD to aid in key recovery. I am happy to say yes and even have a resource for you to use when implementing this.
The document describes how to configure AD to back up recovery information for BitLocker and TPM. You can download the document here.
On a side note, if you are deploying Vista in a pilot or production enviroment, get in contact with us as we maybe able to offer you some extended support!
