Authoritative Restore

Restore from DSRM

 

For this to work Windows Backup must have taken backups for the ntds.dit file.

 

Browsing the Backups and the NTDS.dit file

 

Manual Snapshots of the drive can be done from

ntdsutil: act inst ntds

snapshot create

list all

 

Select the GUID of the backup and Mount it as follows:

 

Mount {GUID}

 

You can then browse the snapshot in the c:\

 

You can then mount the ntds.dit file inside the mounted backup as follows:

 

Exit ntdsutil and run:

 

dsamain -dbpath c:\$SNAP_65168161358_VOLUMEC$\Windows\ntds\ntds.dit -ldapport 5000

 

This will be mounted and then can be accesses from dsa.msc. You need to change domain controller to dc1.contoso.local:5000 to browse the NTDS.dit file.

 

Performing an Authorative Restore

If an OU or user or whatever needed to be restored authorativly do the following.

 

Restart DC in DSRM (Directory Services Restore Mode)

 

Open CMD

 

bcdedit /set safeboot dsrepair

shutdown /r /t 0

Restore AD Objects

  • To enable Active Directory Recycle Bin using the Enable-ADOptionalFeature cmdlet
    Click Start, click Administrative Tools, right-click Active Directory Module for Windows PowerShell, and then click Run as administrator.
    Below is a sample for enabling it for domain.com:
    Enable-ADOptionalFeature –Identity "CN=Recycle Bin Feature,CN=Optional Features,CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=domain,DC=com" –Scope ForestOrConfigurationSet –Target domain.com
     
    Once you have the Recycling Bin for Active Directory you will have to use LDP.exe to restore. By default the container with the deleted objects is not displayed. The following steps will allow you to see the container with the deleted objects.

        
    To display the Deleted Objects container
    1. To open Ldp.exe, click Start, click Run, and then type ldp.exe.
    2. On the Options menu, click Controls.
    3. In the Controls dialog box, expand the Load Predefined pull-down menu, click Return deleted objects, and then click OK.
    4. To verify that the Deleted Objects container is displayed:
      1. To connect and bind to the server that hosts the forest root domain of your AD DS environment, under Connections, click Connect, and then Bind
      2. Click View, click Tree, and in BaseDN, type DC=<mydomain>,DC=<com>, where <mydomain> and <com> represent the appropriate forest root domain name of your AD DS environment.
      3. In the console tree, double-click the root distinguished name (also known as DN) and locate the CN=Deleted Objects, DC=<mydomain>,DC=<com>container, where <mydomain> and <com> represent the appropriate forest root domain name of your AD DS environment.
         
         
        Once you have enabled the container to be displayed, you can now restore deleted objects from Active Directory. Below are the steps to recover a single item from the recycle bin using LDP.exe.
        To restore a deleted Active Directory object using Ldp.exe
    1. Open Ldp.exe from an elevated command prompt. Open a command prompt (Cmd.exe) as an administrator. To open a command prompt as an administrator, click Start. In Start Search, type Command Prompt. At the top of the Start menu, right-click Command Prompt, and then click Run as administrator. If the User Account Control dialog box appears, enter the appropriate credentials (if requested), confirm that the action it displays is what you want, and then click Continue.
    2. To connect and bind to the server that hosts the forest root domain of your AD DS environment, under Connections, click Connect, and then click Bind.
    3. On the Options menu, click Controls.
    4. In the Controls dialog box, expand the Load Predefined drop-down list, click Return Deleted Objects, and then click OK.
    5. In the console tree, navigate to the CN=Deleted Objects container.
    6. Locate and right-click the deleted Active Directory object that you want to restore, and then click Modify.
    7. In the Modify dialog box:
      1. In Edit Entry Attribute, type isDeleted.
      2. Leave the Values box empty.
      3. Under Operation, click Delete, and then click Enter.
      4. In Edit Entry Attribute, type distinguishedName.
      5. In Values, type the original distinguished name (also known as DN) of this Active Directory object.
      6. Under Operation, click Replace.
      7. Make sure that the Extended check box is selected, click Enter, and then click Run
