4. When the deletion is finished, restart ServerXX. In the Shutdown Event Tracker dialog box,
type
Test AD Restore
in the Comment text box, and then click
OK
.
5. When your server begins to restart, press
F8
. Press
F8
several times until the Advanced Boot
Options menu is displayed.
6. In the Advanced Boot Options menu, press the down arrow key to highlight
Directory
Services Restore Mode
, and then press
Enter
.
7. You must log on with the
local
Administrator account and the DSRM password, which
should be Password01. To do so, click
Switch User
, and then type
Administrator
in the User
Name text box and
Password01
in the Password text box. “Safe Mode” is displayed in the
corner of the desktop.
8. Open a command prompt window. You must get a list of the available backups before you
can restore the system state. Type
wbadmin get versions -backuptarget:P:
and press
Enter
.
After a minute or so, a list of backups is displayed. Make note of the version identifier of
the most recent backup, which is the system state backup you created in Activity 13-4.
9. To begin the recovery, type
wbadmin start systemstaterecovery -version:
DateTime
-backuptarget:P:
(replacing
DateTime
with the version identifier you noted in Step 8) and
press
Enter
. When prompted to start the recovery operation, type
y
and press
Enter
.
10. The restoration will probably take several minutes. When it's finished, you must mark
deleted objects as authoritative. Because this server is the only writeable domain controller
running, normally this step isn't necessary, but you should go through the steps so that
you're familiar with the process. With a nonauthoritative restore, you would simply restart
the server to complete the restoration. Do
not
restart your server, however.
11. Type
ntdsutil
and press
Enter
to start this utility. Type
activate instance ntds
and press
Enter
.
Type
authoritative restore
and press
Enter
. At the authoritative restore prompt, type
restore
subtree ou=TestOU,dc=w2k8adXX,dc=com
and press
Enter
. When the Authoritative
Restore Confirmation dialog box opens, click
Yes
. Type
quit
and press
Enter
and type
quit
again and press
Enter
. The restore command specifies the object to restore authoritatively.
The rest of the Active Directory database is stored nonauthoritatively.
To restore the entire database authoritatively, use the command restore
database instead of restore subtree.
12. Close the command prompt window, and restart the server. In the Shut Down Windows
dialog box, type
Restore TestOU
in the Comment text box and click
OK
. Your server might
restart several times to complete the restoration.
13. Log on as the domain Administrator. The system state recovery performs some final tasks,
opens a command prompt window, and displays a “Completed successfully” message. Press
Enter
to continue when prompted.
