Restoring an AD LDS instance that belongs to a configuration set

To completely restore an AD LDS instance that belongs to a configuration set

1. On one of the remaining AD LDS instances in the configuration set, delete the server object representing the AD LDS instance that you want to restore, as follows:
   1. Open a command prompt.
      
   2. At the command prompt, type dsmgmt , and then press ENTER.
      
   3. At the dsmgmt: prompt, type metadata cleanup , and then press ENTER.
      
   4. At the metadata cleanup: prompt, type select operation target , and then press ENTER.
      
   5. At the select operation target: prompt, type connections , and then press ENTER.
      
   6. At the server connections: prompt, type the following command, and then press ENTER:
      
      connect to servercomputername:portnumber
      
      where computername:portnumber represents the AD LDS instance to which you are connecting.
      
   7. At the server connections: prompt, type q , and then press ENTER.
      
   8. At the select operation target: prompt, type list sites , and then press ENTER. Identify the number corresponding to the site in which the server object that you want to delete resides.
      
   9. At the select operation target: prompt, type select site   n , and then press ENTER, where n represents the number identified in the previous step.
      
   10. At the select operation target: prompt, type list naming contexts , and then press ENTER. Identify the number that corresponds to a naming context previously held by the server whose server object you want to delete.
       
   11. Type select naming context   n , and then press ENTER, where n represents the number identified in the previous step.
       
   12. Type list servers in site , and then press ENTER. Identify the number that is associated with the server whose server object you want to delete.
       
   13. Type select server   n , and then press ENTER, where n represents the number identified in the previous step.
       
   14. At the select operation target: prompt, type q , and then press ENTER.
       
   15. At the metadata cleanup: prompt, type remove selected server , and then press ENTER. Click yes to confirm the deletion of the server object.
       
   16. In addition, you must delete the server object from the sites container:
       
       CN=Servers,CN= sitename ,CN=Sites,CN=Configuration,CN={ GUID }
       
       where sitename represents the name of the site in which the server object exists, and GUID represents the globally unique identifier (GUID) of the AD LDS instance.
       
2. Open Backup.
3. On the Action menu, click Recover .
4. Follow the steps in the Recovery Wizard to specify the location of the source backup data and identify the specific backup from which you want to recover instance data.
5. In Select recovery type , click Files and folders , and then click Next.
6. In Select items to recover , browse to and select the folder containing the instance data files. By default, AD LDS database and log files are located in %ProgramFiles%\Microsoft ADAM\ instancename where instancename is the AD LDS instance name.
7. In Specify recovery options , click Alternate location , specify a temporary location for the recovered files, and then click Next .
8. To complete the restore, click Finish .
9. At a command prompt, type the following command, and then press ENTER:
   %windir%\adam\adaminstall /adv
10. Follow the steps in the Active Directory Lightweight Directory Services Setup Wizard.

Additional considerations

• To open Backup, click Start , click Administrative Tools , and then click Backup .
  
• To open a command prompt, click Start , right-click Command Prompt , and then click Run as administrator .
  
• For help with dsmgmt , at a dsmgmt prompt, type ? , and then press ENTER.
  
• If you accidentally start a restore of an AD LDS instance over a currently running AD LDS instance, we recommend that you immediately restart the computer, stop the AD LDS instance, and then perform the restoration again.
