The Distributed Link Tracking Server (TrkSvr) service stores information so files that are moved between volumes can be tracked for each volume in the domain. When enabled, the Distributed Link Tracking Server service runs on each domain controller in a domain. This service enables the Distributed Link Tracking Client service to track linked documents that have been moved to a location in another NTFS volume in the same domain.

The Distributed Link Tracking Server service is disabled by default. If you enable it, you must do so on all domain controllers of a domain. If the Distributed Link Tracking Server service is enabled on a domain controller that is upgraded to a newer version of Windows Server, the service must be re-enabled manually.

If the Distributed Link Tracking Server service is enabled and then later disabled, you must purge its entries in AD DS. For more information, see article 312403 in the Microsoft Knowledge Base.

If the Distributed Link Tracking Server service stops or if you disable it, links that are maintained by the Distributed Link Tracking Client service eventually become less reliable.

The Distributed Link Tracking Server service is part of the AD DS server role.

This service is available on a Server Core installation of Windows Server 2008 R2 in addition to the Standard, Enterprise, and Datacenter editions of Windows Server 2008 and Windows Server 2008 R2.
