NTFS permission information for a DFS share takes longer than expected to display in Windows 7 or in Windows Server 2008 R2

Consider the following scenario:
  • You have a computer that is running Windows 7 or Windows Server 2008 R2.
  • You access a Distributed File System (DFS) share by using a nested DFS link from the computer. For example, example, assume that the following are domain-based DFS namespaces:
    • DFSRoot1: \\Domain name\DFSRoot1
    • DFSRoot2: \\Domain name\DFSRoot2
    Also, assume that the \\Domain name\DFSRoot1\LinkA DFS link maps to DFSRoot2. Additionally, assume that the \\Domain name\DFSRoot2\LinkB DFS link maps to the following shared folder:
    \\Server name\share name
    You access the shared folder through the following DFS path:
    \\Domain name\DFSRoot1\LinkA\LinkB
  • You open the Properties dialog box to check the NTFS permissions for the DFS share.
In this scenario, the computer takes longer than expected to display the permissions information. Specifically, the computer takes about 6-10 seconds to display the NTFS permissions information.

  • This issue does not occur if you access the DFS share through one of the following paths:
    \\Server name\share name
    \\Domain name\DFSRoot2\LinkB
  • This issue typically occurs when the domain controllers in the domain are in different remote sites and resolve the Fully Qualified Domain Name (FQDN) of the domain from a site. This behavior causes a workstation to contact a domain controller in another site. For example, the query time is longer than expected for the following domain controllers: 
    • Domain controller DC1: (site 1)
    • Domain controller DC2: (site 2)
    • Work station WS: (site 1)
    This occurs because one of the domain controllers is in a remote site and Windows 7 and Windows Server 2008 R2 implement Internet Engineering Task Force (IETF) RFC 3484. Therefore, WS contacts DC2 to resolve the FQDN of the domain.

    969029   The functionality for source IP address selection in Windows Server 2008 and in Windows Vista differs from the corresponding functionality in earlier versions of Windows


This issue occurs because the system returns the FQDN of the domain instead of the host name of a nested DFS path. Additionally, when you check the NTFS permissions, the system queries the Domain Name System (DNS) records, and these may point to any domain controller in the domain.
