SYMPTOMS
Consider the following scenario:
 * You have a Windows Server 2003-based member server.
 * On the member server, you try to access a Distributed File System (DFS) root in the DFS Microsoft Management Console (MMC) snap-in.

In this scenario, you may receive the following error message:

The specified DFS root does not exist.

Additionally, when you view the permissions of the DFS root in the Active Directory Users and Computers MMC snap-in, the member server security identifier (SID) is shown as unresolved.

You may experience this issue if the following conditions are true:
 * The member server that hosted the DFS root was taken offline. Additionally, the member server computer account was deleted.
 * A new member server is brought online that uses the same computer name as the member server that was taken offline.



CAUSE
This issue occurs because the SID of the DFS root is associated with the member server computer account that was deleted.



RESOLUTION
To resolve this issue, follow these steps:  Click Start, point to Programs, point to Administrative Tools, and then click Distributed File System. In the console tree, click the DFS root. In the details pane, right-click the problematic DFS root target, and then click Remove Target. Click Yes when you receive the following error message:

The following error occurred during deleting the DFS root on.

Do you want to forcibly remove the DFS root?
