Backing up active directory

I'm trying to backup active directory for a DR test.   Through Windows 2003 server backup utility.
This is done in directory services restore mode F8.

I keep getting "NTDS" has reportd an error 0x800423f4.  This is part of the system State.

I did a google search and nothing comes up.
Any suggestions.

Hi autumn801,

the backup itself isnt done in directory restore mode just the restore....;en-us;241594&sd=tech

Check out this article.  I'm not sure why you're using DSRM to "Back Up" AD.  You can do it running normally.  To restore you need to be in DSRM. 
NTDIS is part of the system state. The actual database file, is %SystemRoot%\ntds\NTDS.DIT. The ntds.dit file is the heart of Active Directory including user accounts. Active Directory's database engine is the Extensible Storage Engine ( its a play off of the old Jet database from Access and Exchange). I back it up with windows backup- mainly becasue that the only thing I have ever been able to restore it with! Once I did a bad promotion ant it killed ad- luckly I had a windows back up and I could restore just AD,

Heres a non microsoft explanation of how to corectly back up the AD on a domian controller.

Microsoft speak give me headaches!
good luck

Thanks for the advice,  but keep in mind I am restoring back to a brand new machine with different hard ware.
I'm following:  How to perform a disaster recovery restoration of AD on a computer with a different hardware configuration - Q263532.

This is being done backing up and restoring certain OU's that were deleted.  We are doing DR and restoring to a machine that will be the only DC in the domain for DR testing purposes.  Then the other groups will create other stand alone servers to see if they can join the domain and log in etc.....

I'll try again.

Keep in mind this is windows 2003 server.
same points still stand
Jay_Jay70's comment should work but are you getting that error on the backup or on the restore?
