Author­itative Restore

Hvad er det
Tillader admini­str­atoren at recover en domain contro­ller, restore den til et bestemt tidspunkt, eller markere objekter i AD til at være author­itative
Auth­ori­tative betydn­ing
"For example, you might need to perform an author­itative restore if an admini­strator inadve­rtently deletes an organi­zat­ional unit containing a large number of users. If you restore the server from tape, the normal replic­ation process would not restore the inadve­rtently deleted organi­zat­ional unit. Author­itative restore allows you to mark the organi­zat­ional unit as author­itative and force the replic­ation process to restore it to all of the other domain contro­llers in the domain."
Komm­and­oer
Restore database
"­Marks the entire Ntds.dit (both the domain and config­uration naming contexts held by the domain contro­ller) as author­ita­tive. The schema cannot be author­ita­tively restor­ed."­
Restore database verinc %d
Marks the entire Ntds.dit (both the domain and config­uration naming contexts held by the domain contro­ller) as author­itative and increments the version number by % d . Use this option only to author­ita­tively restore over a previous, incorrect, author­itative restore, such as an author­itative restore from a backup that contains the problem you want to restore over.
Restore subtree %s
"­Marks subtree (and all children of subtree) as being author­ita­tive. The subtree is defined by using the fully distin­guished name of the object."
Restore subtree %s verinc %d
Marks subtree (and all children of subtree) as being author­itative and increments the version number by % d . The subtree is defined by using the fully distin­guished name of the object. Use this option only to author­ita­tively restore over a previous, incorrect, author­itative restore, such as an author­itative restore from a backup that contains the problem you want to restore over.
