When you use the Windows 2000 DFS (Distributed File System) Wizard to create a new DFS root, you receive:
The following error occurred while creating DFS root. Cannot create a file when that file already exists.

To fix the problem, use the DFSutil.exe tool, from the Support\Tools folder on the Windows 2000 CD-ROM, to clear the previous information:
Re-run the DFS Wizard.
