- Make sure that sufficient free disk space is available on the volumes that host the Active Directory database, and then retry the operation. Follow these steps to free additional disk space:
- Move unrelated files to another volume.
- Perform a system state backup. This process reduces the size of the transaction log files.

- Perform an offline defragmentation of Active Directory. For more information, click the following article number to view the article in the Microsoft Knowledge Base: 232122 Performing offline defragmentation of the Active Directory database
- Make sure that the physical drives that host the Ntds.dit file and the transaction log files do not have NTFS file system compression turned on. To confirm this, right-click the drive letter in My Computer, and then make sure that the Compress drive to save disk spacecheck box is not selected.
- Make sure that the physical drives that host the Ntds.dit file and the transaction log files are specifically excluded from remote and local antivirus programs. See your antivirus software documentation for more information.
- If the destination domain controller contains the global catalog, and the error occurs in one of the read-only partitions, use one of the following methods to help resolve the problem:
Method 1Use the rehost option of the Repadmin.exe tool to rehost the affected partition. The Repadmin.exe tool is included with Windows Server 2003 SP1. To do this, type the following at a command prompt, where
domain_controller is the name of the destination domain controller, and
good_source_domain_controller_name is the name of another domain controller:repadmin /rehost domain_controller naming_context good_source_domain_controller_name
Method 2To configure the domain controller so that it is no longer a global catalog server, follow these steps:
- Click Start, point to
Administrative Tools, and then click Active Directory Sites and Services.
- Locate the
Default-First-Site-Name\Servers\domain_controller_name\NTDS Settings subtree.
- Right-click NTDS Settings, and then click Properties.
- Click to clear the Global Catalog check box. Click OK.
Method 3If the error occurs in a program partition, use the Ntdsutil.exe tool to change the replica that hosts the program partition. For more information about Active Directory Directory Services Maintenance Utility (Ntdsutil.exe), visit the following Microsoft Web site:
- Click Start, point to
- Use a third-party utility, such as the FileMon utility, to determine if a program or a user is accessing the Active Directory database, the transaction log files, or the Edp.tmp file. If file access activity exists, stop the services that are responsible for the activity. For more information about the FileMon utility, visit the following Sysinternals Web site:
- Determine if the problem is related to the parent of the Active Directory object on the destination domain controller. To do this, follow these steps:
251343 Manually initializing the SD propagator thread to evaluate inherited permissions for objects in Active Directory
- On the source domain controller, temporarily move the object that is referenced in Event ID 1084 to an organizational unit (OU) container. The OU must be unrelated to the current container. For example, move the object to a new container off the root of the domain.
- If replication is completed after you move the object, move the object back to its original container.
- Force the security descriptor propagator to rebuild the object container ancestry in the database that exists on both the source and destination domain controllers. To do this, follow these steps:
- Make sure that the Windows Server 2003 Support Tools are installed. The Support Tools are available on the Windows Server 2003 CD-ROM in the Support\Tools folder. Double-click the Suptools.msi file to install the tools.
- Click Start, click
Run, type ldp, and then click
- Click Connection, click
Connect, and then type the name of the server that you want to connect to. You will connect over port 389 for Active Directory.
- Click Connection, click
Bind, and then type your administrative user name, password, and domain. (You must use domain administrator or enterprise administrator credentials.) Click OK.
- On the Browse menu, click
Modify. Leave the DN text box blank. In the
Attribute text box, type
FixUpInheritance. Click Yes in the
Value text box.
- In the Operation area, click
- Click Enter to populate the
Entry List area. [Add]fixupinheritance:yes appears in the Entry List area.
- Click Run. The right pane shows a "Modified" status, and the security descriptor propagator starts. The runtime for the security descriptor propagator depends on the size of the Active Directory database. The process is complete when the DS Security Propagation Events counter in the NTDS Performance object returns to zero.
- Click Close, click
Connection, and then click Exit.
- On the source domain controller, type repadmin /showmeta distinguished_name_path at a command prompt, and then view the object metadata for the distinguished name path that is referenced in Event ID 1084. Repeat this step on the destination domain controller. Look for inconsistent values that include, but are not limited to, the following:
- Incorrect names and numbers of attributes that appear on the object
- Incorrect originating time or date stamps
- Incorrect local update sequence numbers (USN)
To use the Repadmin.exe tool when the distinguished name path refers to a live object, type the following at a command prompt:repadmin /showmeta remote_domain_controller_name distinguished_name_path_of_reference _objectIf the object is in a deleted objects container or if you cannot use the Repadmin.exe tool to find the object, use the object's GUID reference to find the object. This GUID is referenced in Event ID 1084. To do this, type the following at a command prompt:repadmin /showmeta remote_domain_controller_name “GUID_for_the_object that_is_referenced_in_Event_ID_1084"For example, if Event ID 1084 and Event ID 2108 reference an object where the GUID is b49cd496-98a2-4500-bb08-58550c2f79ac, type:repadmin /showmeta "<GUID=b49cd496-98a2-4500-bb08-58550c2f79ac>"Note The quotes and brackets are required.
- Obtain the most recent Ntdsutil.exe tool by installing the latest service pack for your operating system. Use the Ntdsutil.exe tool to perform an integrity check of the Active Directory database on the source domain controller.
Before you start the computer in Directory Services Restore Mode, obtain the password for the offline administrator account. If you do not know the administrator account password, reset the Directory Services Restore Mode password before you start in this mode. On domain controllers that are running Windows 2000 Service Pack 2 (SP2) and later, use the Setpwd.exe command. The Setpwd.exe command is located in the %Systemroot%\System32 folder. On Windows Server 2003-based domain controllers, use the Ntdsutil Set Directory Services Restore Mode Password command. For more information about Directory Services Restore Mode, click the following article number to view the article in the Microsoft Knowledge Base:258062 "Directory Services cannot start" error message when you start your Windows-based or SBS-based domain controllerFor more information about how to change the password in Windows 2000 Server, click the following article number to view the article in the Microsoft Knowledge Base:239803 How to change the Recovery Console administrator password on a domain controllerFor more information about how to change the password in Windows Server 2003, click the following article number to view the article in the Microsoft Knowledge Base:322672 How to reset the Directory Services Restore Mode administrator account password in Windows Server 2003
- Restart the source domain controller, and then press F8 to start Directory Services Restore Mode. At the command prompt, type
ntdsutil files integrity, and then press ENTER. This command confirms the integrity of the database.
- If the Ntdsutil tool reports that the database is corrupted, and you have replicas of the naming contexts on the source domain controller, force a demotion of the source domain controller, and then re-promote it after you verify the integrity of the drivers, the firmware, and the physical drives that host the Active Directory database and the transaction log files.
- If the database is corrupted, and no replicas of the naming context on the source domain controller exist, restore the newest system state. Use the NTDSutil.exe tool to confirm the integrity of the database again. If you still receive a corruption message, restore older backups until you can confirm the integrity of the domain controller.
- If the database is still corrupted, restore the most recent system state backup, and then, at a command prompt, type:ntdsutil files recoverUse the NTDSutil.exe tool confirm the integrity of the database again. If the database passes the integrity check, perform an offline defragmentation of the disk partition.
For more information, click the following article number to view the article in the Microsoft Knowledge Base:232122 Performing offline defragmentation of the Active Directory DatabaseTo perform an integrity check of the database, type the following at a command prompt, and then press ENTER, where
database_name is the name of the Active Directory database:esentutl.exe /g database_nameFinally, use the Start Windows Normally option to restart the computer, and then retry replication from the source domain controller to the affected destination domain controller. If the database fails the integrity check, the domain controller must be discontinued. You use the Active Directory Migration Tool (ADMT) to migrate objects. You can also use the Ldifde.exe and Csvde.exe tools to export objects that you will import to a new destination domain controller. For more information about how to use the ADMT, click the following article numbers to view the articles in the Microsoft Knowledge Base:326480 How to use Active Directory Migration Tool Version 2 to migrate from Windows 2000 to Windows Server 2003For more information about how to use the Ldifde.exe and Csvde.exe tools, click the following article numbers to view the articles in the Microsoft Knowledge Base:237677 Using LDIFDE to import and export directory objects to Active Directory327620 How to use Csvde to import contacts and user objects into Active Directory298882 The new command-line tools for Active Directory in Windows Server 2003
- If these steps do not succeed, and the replication error continues, demote the domain controller, confirm the integrity of the physical drives and the volumes that host the Ntds.dit file and the disk subsystem, and then promote the domain controller again. Use the same computer name.
- Use the ntdsutil files compact command to perform an offline defragmentation of the Active Directory database. For more information, click the following article number to view the article in the Microsoft Knowledge Base: 232122 Performing offline defragmentation of the Active Directory Database
- At the command prompt, type ntdsutil "semantic database analysis" "go", and then press ENTER.
Note The quotation marks in this example are required to run the semantic database analysis command by using a single command line argument.
If errors are reported, type ntdsutil go fixup, and then press ENTER.
Note The semantic database commands do not perform lossy repairs on Active Directory databases like the pre-Windows Server 2003 Service Pack 1 Ntdsutil File Repair or Esentutl /p commands.
