Consider the following scenario:
3-Oct-2013: Domain Admin created a new user called NBU_User inside HQ_Users organizational unit (OU). The distinguished name looked like this:
CN=NBU_User,OU=HQ_Users,DC=com,DC=testdomain
 
4-Oct-2013: NetBackup Admin ran AD GRT backup.
 
5-Oct-2013: Domain Admin moved NBU_User from HQ_Users to HQ_Administrators OU.
 
6-Oct-2013: Domain Admin deleted NBU_User from Active Directory.
 
7-Oct-2013: Now he needed the user back.
 
7-Oct-2013: NetBackup Admin performed AD GRT Restore. The user object did get created again, but without attributes. 
 
The restore itself failed:
MS-Windows policy restore error(2808)
10/8/2013 7:58:33 PM - Info tar32(pid=0) done. status: 5: the restore failed to recover the requested files  
10/8/2013 7:58:33 PM - Error bpbrm(pid=5068) client restore EXIT STATUS 5: the restore failed to recover the requested files

By using ldp.exe tool, we could locate the deleted user, which now resided in the Deleted Objects container (assuming it has not gone past the tombstone lifetime).
 
The ldp.exe tool also showed some of the user's attributes, including lastKnownParent. In our case it pointed to: OU=HQ_Administrators,DC=com,DC=testdomain
 
Solution:
Move the partially restored user object to the original OU (OU=HQ_Users,DC=com,DC=testdomain) and run the restore again.
 
Tips:
Before running the restore, run the following commands on the destination client to increase ncfgre, ncfrai, and ncf logging level, respectively:
<install dir>\veritas\netbackup\bin\vxlogcfg -a –p 51216 –o 352 –s DebugLevel=6
<install dir>\veritas\netbackup\bin\vxlogcfg -a –p 51216 –o 158 –s DebugLevel=6
<install dir>\veritas\netbackup\bin\vxlogcfg -a –p 51216 –o 309 –s DebugLevel=6
 
Run the restore again, and run this command to obtain the ncfgre log:
<install dir>\veritas\netbackup\bin\vxlogview -p 51216 -i 352 -t 00:30:00 > c:\ncfgre.log
 
Then return the logging level back to default (1):
<install dir>\veritas\netbackup\bin\vxlogcfg -a –p 51216 –o 352 -s DebugLevel=1
<install dir>\veritas\netbackup\bin\vxlogcfg -a –p 51216 –o 158 –s DebugLevel=1
<install dir>\veritas\netbackup\bin\vxlogcfg -a –p 51216 –o 309 –s DebugLevel=1
