SYSTEMS AFFECTED
OU BackUp and Restore
PROBLEM
Hsiao Leng found following. He carried out some tests on OU
Backup and Restore. First he created two OU named as "Test
Restore" and "Testing", and backup the "system state data".
Later, he deleted the "Test Restore" and "Testing" OU, and
carried out a restore perform the following steps:
- Boot up to "Directory Services Restore Mode"
- Logon to Administrator account
- Run ntdsutil, and type authoritative restore
- At the authoritative restore prompt, type restore subtree
OU=Testing,DC=Lab,DC=Solutions and hit Enter.
- The Testing OU restored successfully.
- At the authoritative restore prompt, type restore subtree
OU=Test Restore,DC=Lab,DC=Solutions and hit Enter.
- This time, the Test Restore OU cannot be restored and gave
an error of illegal syntex.
- Have changed the syntex to restore subtree OU="Test Restore"
DC=Lab,DC=Solutions, or restore "subtree OU=Test Restore,
DC=Lab,DC=Solutions", or restore 'subtree OU=Test Restore,
DC=Lab,DC=Solutions', or restore subtree OU='Test Restore',
DC=Lab,DC=Solutions
but still can't restore.
SOLUTION
It looks like the only thing that was not tried after booting to
the F8 screen in safemode and restoring a copy of the AD was to
use the following statement:
restore subtree "OU=Test Restore,dc=mydomain,dc=myroot,dc=com"
The subscribers use of quotations below in an attempt to pass the
entire argument to the 'restore subtree' command failed to try
using quotations in the above manner. After using the above
syntax the "syntax error" went away and the OU named "Test
Restore" restored to the Active Directory properly.
