SUMMARY

This step-by-step article describes how to configure a domain Encrypting File System (EFS) recovery policy.

You can use the Windows 2000 EFS to encrypt files to prevent unauthorized individuals from viewing the contents of the files. To encrypt and decrypt files, a user must have a file encryption certificate. If the file encryption certificate is lost or damaged, access to the files is lost.

Data recovery is possible through the use of a recovery agent. A user account of a trusted individual can be designated as a Recovery Agent so that a business can retrieve files in the event of a lost or damaged file encryption certificate or to recover data from an employee that has left the company.

One of the many advantages of using Windows 2000 domains is that you can configure a domain EFS recovery policy. In a default Windows 2000 installation, when the first domain controller (DC) is set up, the domain administrator is the specified recovery agent for the domain. The domain administrator can log on to the first DC in the domain, and then change the recovery policy for the domain.

If you want to create additional recovery agents, the user accounts must have a file recovery certificate. If available, a certificate can be requested from an enterprise CA that can provide certificates for your domain. However, EFS does not require a CA to issue certificates, and EFS can generate its own certificates to user and to default recovery agent accounts.
