You may have to turn off the Encrypting File System (EFS) on the computer. For example, when a computer that is running Windows 2000 Professional is a member of a Microsoft Windows NT 4.0-based domain, you may have to turn off the EFS on the computer because the domain administrator cannot recover encrypted files. A Windows NT 4.0-based domain has no way to specify the use of the Domain Encrypted Data Recovery Agent.
