The SIS reviews existing permissions on objects stored in Active Directory, and then applies a more efficient security descriptor on those objects.
The SIS starts automatically identified by event in the directory service event log when upgraded domain controllers first start the Windows Server operating system. You benefit from the improved security descriptor store only when you log an event ID event message in the directory service event log: This event message indicates that the single instance store operation has completed and serves as a queue the administrator to perform of offline defragmentation of the Ntds.
The offline defragmentation can reduce the size of a Windows Ntds. For more information about how to defragment the Active Directory database, click the following article number to view the article in the Microsoft Knowledge Base:.
Otherwise, incrementally delete distributed link tracking objects from Active Directory. For more information, click the following article number to view the article in the Microsoft Knowledge Base:. If you bulk delete thousands of DLT objects or other objects, you may block replication because of a lack of version store. EXE to perform an offline defragmentation of the Ntds. Configure the best practice organizational unit structure.
Microsoft recommends that administrators actively deploy the best practice organizational unit structure in all the Active Directory domains, and after they upgrade or deploy Windows Server domain controllers in Windows Domain mode, redirect the default containers that earlier-version APIs use to create users, computers, and groups to an organizational unit container that the administrator specifies. For additional information about the best practice organizational unit structure, view the "Creating an Organizational Unit Design" section of the "Best Practice Active Directory Design for Managing Windows Networks" white paper.
Repeat steps 1 through 10 as required for each new or upgraded Windows Server domain controller in the forest and step 11 Best Practice organizational unit structure for each Active Directory domain.
Before you upgrade Windows domain controllers to a production Windows domain, validate and refine your upgrade process in the lab. If the upgrade of a lab environment that accurately mirrors the production forest performs smoothly, you can expect similar results in production environments.
For complex environments, the lab environment must mirror the production environment in the following areas:. An understanding of the upgrade process and complexity of the environment combined with detailed observation determines the pace and degree of care that you apply to upgrading production environments. Environments with a small number of domain controllers and Active Directory objects connected over high availability wide area network WAN links might upgrade in only a few hours.
You may have to take more care with enterprise deployments that have hundreds of domain controllers or hundreds of thousands of Active Directory objects. In such cases, you may want to perform the upgrade over the course of several weeks or months. On domain controllers with insufficient disk space, use the following steps to free up additional disk space on the volume that hosts the Ntds.
Delete any user or memory dump files. Temporarily remove or relocate files that you can access from other servers or easily reinstall. Delete old or unused user profiles.
To do so, click Start , right-click My Computer , click Properties , click the User Profiles tab, and then delete all the profiles that are for old and unused accounts. Don't delete any profiles that may be for service accounts. Perform an offline defragmentation. An offline defragmentation of the Ntds. Perform the offline defrag by using other local volumes if one is available.
Or, use space on a best connected network server to perform the offline defragmentation. If the disk space is still not sufficient, incrementally delete unnecessary user accounts, computer accounts, DNS records, and DLT objects from Active Directory. Active Directory does not delete objects from the database until tombstonelifetime number of days by default, 60 days have passed and the garbage collection completes.
If you reduce tombstonelifetime to a value lower than end-to-end replication in the forest, you may cause inconsistencies in Active Directory. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info.
