You are the administrator of a Windows 2000 domain that has three domain controllers. Each day, you use Windows Backup to perform full backups of each domain controller. You run a script to make changes to account information in Active Directory. As a result of errors in the script, the incorrect user accounts are modified. Active Directory replication then replicates the changes to the other two domain controllers. You want to revert Active Directory to the version that was backed up the previous day. What should you do?
