When a computer is a member of a domain, DPAPI has a backup mechanism to allow unprotection of the data. When a Master Key is generated, DPAPI communicates with a domain controller. Domain controllers have a domain-wide public/private key pair, associated solely with DPAPI. The local DPAPI client gets the domain controller public key from a domain controller by using a mutually authenticated and privacy protected RPC call. The client encrypts the Master Key with the domain controller public key. It then stores this backup Master Key along with the Master Key protected by the user's password.
Periodically, a domain-joined machine will try to send an RPC request to a domain controller to back up the user’s master key so that the user can recover secrets in case his or her password has to be reset. Although the user's keys are stored in the user profile, a domain controller must be contacted to encrypt the master key with a domain recovery key.
