Symptoms

Consider the following scenario:

  • You install the Distributed File System (DFS) Namespace service role on a computer that is running Windows Server 2008 or Windows Server 2008 R2.

  • The DFS server is hosted either in a domain-based DFS or in a standalone DFS environment.

  • The DFS environment may include Windows Server 2003-based DFS server along with Windows Server 2008-based or Windows Server 2008 R2-based DFS server, which is typically the case during migration phase of DFS servers.

  • You enable Access-based Enumeration (ABE) for the DFS V1 namespace share. Then, you set specific permissions on the DFS link folders within the share.

  • You use a non-DFS utility to set permissions on intermediate folders. For example, you use Icacls.exe to set permissions.

  • You restart the DFS Namespace service or restart the computer.

In this scenario, the permissions of some DFS folders are incorrectly reset.

Cause

This issue occurs because of a logic error in the DFS Namespace service. This issue occurs when the service sets an Access Control List (ACL) to the DFS folders in a DFS version 1 namespace during the service startup process.
