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? （）

Your network consists of a single Active Directory domain. All servers run Windows Server 2003 Service
Pack 2 (SP2). The domain contains two domain controllers named DC1 and DC2. DC1 is located in Montreal and DC2 is located in Seattle. Each domain controller has a dedicated hard disk that contains only the Active Directory database and log files.
Each night, you back up the system state on all domain controllers.
On DC2, the hard disk that contains Active Directory fails.
You replace the failed hard disk on DC2.
You need to restore domain controller functionality on DC2. The solution must minimize replication traffic between Montreal and Seattle.
