Ah. I apologize.
So, there should not be a need to do restore twice?

I did not say "System State" and "Windows Directory"
I said: "System State" and "System Disk / Boot Volume" (the latter is the
volume that CONTAINS the Windows directory)

Thanks a bunch Joge.
I am doing W2K3 restore. I didn't know about the bit about SYSVOL restore,
but I assumed it would be backed up with System State. I am going to try to
do System State AND the Windows Directory today, and see how that goes, as
doing just system state hasn't gone well so far.
Also, one thing that I noticed is that, when doing restore using ntbackup,
when I select the file -> System state. The five items show up in the right
pane with their correct modified date, but Active Directory shows up without
a date, hence blank. Am I correct to assume that it is because the host
machine is not a DC, that is why no presence of AD modified date while
restoring?

Hi,
You have not told us if you are using W2K or W2K3 AD... There is a tiny
difference between the two...
When doing a bare metal restore I always advise to restore a backup of the
System Disk (in MS terms it is called the boot volume, and for both it means
the volume with the WIndows/Winnt directory) AND the System State...
In W2K3 restoring the system state also rebuilds the SYSVOL structure, no
matter the location of it... When backing up the system state on a w2k DC,
you should also backup the SYSVOL structure with it. Why?
The SYSVOL structure is like:
SYSVOL <------S
DOMAIN <----- A
STAGING <----- B
DOMAIN <----- B
STAGING AREAS <----- B
<DOMAIN NAME> <----- B
SYSVOL <----- B
<DOMAIN NAME> <----- B
In W2K3 when restoring the system state the structure mentioned above will
be restored correctly.
In W2K when restorin the system state the structure mentioned above will NOT
be restored correctly! In fact it will only restore "A". It will not restore
"B".
So in W2K3 it suffices to select the system state to also restore the SYSVOL
structure
In W2K to restore the SYSVOL structure I advise to select at backup the
System State AND the SYSVOL structure starting at "S"
So if you are using the default AD/SYSVOL paths and if you restore the
system disk and the system state everything will be OK as the sysvol
structure is backupped with the system disk.
If you have AD/SYSVOL on other volumes, for W2K, I advise to backup at least
the System Disk, the System State and additionally the SYSVOL structure
starting at "S". This is especially important when doing a bare metal
restore.
IMHO, for a DC you should always at least backup the system disk and the
system state, and if it is a w2k DC also backup the FULL SYSVOL structure.
Remember, if you are restoring the first DC in a certain domain you need to
restore AD non-auth. and SYSVOL auth. (for the latter in other words as
PRIMARY)
Hope this helps you!
Cheers,
Jorge

Subject: [ActiveDir] Restore twice in Disaster Recovery?
Hello All!
I have researched this question quite a bit, but have not found a solid
answer as to why or how this would be done.
I am doing a disaster recovery test on VMs, to eliminate the part of
'dissimilar hardware' or to simulate 'Identical hardware' in real life
scenario. But I am running into some trouble while doing this, and hope that
some of you can help me out here.
Here is what I have:
A single DC that holds all FSMO roles.
I am using ntbackup to take only System State backup of the good DC. <all
paths default>
Here is what I do to restore:
Got a freshly installed 2003 standalone server.
Hooked it into a hub to get network connectivity.
Give it the same ip as my good DC
In normal mode, while logged in as local admin, ran ntbackup, and restored
the file created from orginial DC with defaults. <To original location,
create junctions> and restarted.
In normal mode, it gives an error 0xc000018e, and says to restart in DSRM.
Upon rebooting in DSRM, DC asks to activate windows, and after passing that,
when I ran ntdsutil, it does not pass file integrity.
Upon closer inspection, in Windows\NTDS, I have only ntds.dit and one log
file, when originally I am supposed to have more than that just two files.
--
Now I can't boot up into the normal mode, and I tried to do a restore second
time while being in DSRM, but that didn't help either.
I am thinking to blow away this copy and reinstall again and do ntbackup
again, but should I do the restore twice before rebooting?
I read in the list archives that while restoring, do restore to original
location once and second time to an alternate location. What is that about?
Also, would doing a back up of System State AND the whole C Drive help?
Thanks a lot in advance!
