Mark works as a Network Administrator for NetTech Inc. The company has a Windows 2003 Active Directory domain-based network. The domain consists of four domain controllers, six Windows 2003 member servers, and 500 Windows XP Professional client computers. The PKI infrastructure is already configured on the network. The current configuration of the network allows only managers to use EFS on local computers. Sometimes Mark faces problems when managers lose their private keys due to the user profile becoming corrupt or being lost. Due to this, the files that were persistently encrypted by using the corresponding public key are inaccessible. He wants to restore access to the encrypted files as quickly as possible. What will he do to accomplish the task?
