Your network consists of a single Active Directory domain. All network servers run Windows Server 2003 Service Pack 2 (SP2). Your organization has a storage area network (SAN). All shared folders on file servers are stored on the SAN. The Change permission for all shared folders is assigned to Domain Users. Different NTFS permissions are also applied to the shared folders. You perform a daily full backup of all the files stored in the shared folders. A file server fails and requires several hours to repair. You need to provide users access to the shared folders that were on the failed file server as quickly as possible. Existing permissions must be retained for all files. What should you do? （）
