SYMPTOMS
You configure a stand-alone Distributed File System (DFS) root in a Microsoft Windows Server 2003 cluster environment. When you turn on the DfsDnsConfig registry key to enable fully qualified domain name (FQDN) referrals, the DFS referral queries may respond with the NetBIOS name and not with the FQDN of the DFS root. For example, the queries may respond with \ \.

Additionally, when you try to access a DFS resource from a trusted domain by using the FQDN of the DFS resource, you may receive the following error message:

Configuration information could not be read from the domain controller, either because the entire machine is unavailable, or access has been denied.

Note This problem does not occur on stand-alone Microsoft Windows Server 2003-based computers that use a stand-alone DFS root.

MORE INFORMATION
By default, DFS uses NetBIOS name resolution for all network shares that are configured in the DFS namespace. In this case, DFS clients that only support NetBIOS name resolution can locate and connect to the shares in the DFS namespace. However, DFS clients that do not use NetBIOS name resolution may not be able to resolve the name of a DFS share.

DFS can also operate in a Domain Name System (DNS)-only environment, where all the computers use FQDNs for name resolution. To operate in that environment, you must add the DFSDnsConfig registry key on each server that participates in the DFS namespace. Add the key to the servers before the DFS namespace is built. In that way, clients will see FQDNs when the clients are referred to other servers as part of the DFS referral process.

You can use the Dfsutil.exe command-line tool to verify DFS internal information. To do this, follow these steps:
 * 1) Click Start, click Run, type cmd, and then click OK.
 * 2) At the command prompt, type dfsutil /pktinfo.
 * 3) If this problem exists, the tool responds with \ \  instead of \ \.

For more information about how to use the Dfsutil.exe tool, type dfsutil /? at the command prompt.
