You cannot perform a system state backup on a domain controller that is running Windows Server 2003 SP1 (913642)

SYMPTOMS

You try to perform a system state backup on a domain controller that is running Microsoft Windows Server 2003 Service Pack 1 (SP1). However, the process that backs up the Active Directory database and the Active Directory log files fails. Additionally, an error message that resembles the following appears in the backup log:

Operation: Backup
Active backup destination: File
Media name: "sysstate.bkf created DD/DD/YYYY at HH:MM AM|PM"

Volume shadow copy creation: Attempt 1.
"NTDS" has reported an error 0x800423f0.
This is part of System State. The backup cannot continue.

Error returned while creating the volume shadow copy:800423f0.
Aborting Backup.

CAUSE

This problem occurs if the Volume Shadow Copy Service (VSS) does not perform a volume snapshot of the drive that contains the log files. The VSS does not perform a volume snapshot if the following conditions are true:

Either the DIT volume or the volume that contains the Active Directory log files resides on the system drive.
The Active Directory log files have been moved from the system drive, and the DIT volume resides on the system drive.

The following table lists the outcome for five scenarios in which the DIT volume, the operating system, and the log files are stored on a computer. You cannot create system state backups for scenarios 3 and 4 on a computer that is running Windows Server 2003 SP1.

Scenarios	1	2	3	4	5
Operating System	C	C	C	C	C
Database	C	D	C	D	D
Log files	C	E	D	C	D
Outcome	Success	Success	Failure	Failure	Success

Note Letters C, D, and E represent drives on the domain controller. The drive letter assignments do not have to match the drive letter assignments in the table. The drive letters in the table indicate the relative placement of the operating system, the database, and the log files.

You may not experience this issue in the original release version of Windows Server 2003.

WORKAROUND

To work around this problem, use one of the following methods:

Store the DIT volume, the operating system, and the log files on the domain controller, as shown in scenarios 1, 2, or 5 in the "Cause" section.

Note Drive letter assignments on the domain controller do not have to match the letter assignments in the scenarios table.

You may have to relocate a DIT volume or the Active Directory log files from a domain controller that has been restarted in directory services repair mode. For more information about how to move the database and to move the log files, click the following article number to view the article in the Microsoft Knowledge Base:
816120 How to use Ntdsutil to manage Active Directory files from the command line in Windows Server 2003
If a domain controller configuration corresponds to scenarios 3 and 4, use the Ntbackup utility to select any file on the volume that includes Active Directory database files. This file can be a dummy file. In this configuration, this volume is backed up by the Ntbackup utility.
