Cannot enumerate a non-container.
Windows 2000 organizes a network logically as a hierarchy. An application program can request a list of all resources below a specified network resource in the hierarchy, but in this case an application specified a network resource at the bottom of the hierarchy.
If you have a user interface, retry the request with a different network resource specified (for example, the resource at the root of the tree). Otherwise, contact the supplier of the running application.
