Article ID: 978324 - View products that this article applies to.
After you install the Distributed File System (DFS) Replication role on a failover cluster node that is running Windows Server 2008 R2, the Clussvc.exe process uses 20 percent to 90 percent of the CPU. The cluster is configured to use hundreds or to use thousands of resources and groups. These resources and groups may not be related to DFS Replication.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
