SYMPTOMS

When you try to mount a directory to a WebDAV server by using the Web DAV client in Windows Vista, the attempt may fail if do not have Read permission on the parent folders of the WebDAV directory. The mount succeeds in Windows Vista if the user who is trying to access the WebDAV resource has Read permission on the root of the drive where the WebDAV share is located. This behavior does not occur if you are using Windows XP with Office 2003 is installed. This is also a problem if the WebDAV share is SSL-based.

For example, you try to use the Add Network Location option in Network Places to access a WebDAV server such as http://server/Root/Share/SubShare. You will not be able to access a WebDAV directory that is located several levels deep if you do not have Read permission to any of the parent directories. These directories may include one of the following:
  • /
  • /Root
  • /Root/Share
Additionally, the WebDAV share might point to a virtual directory that is not located on the root of the server from which the WebDAV share is shared from.

CAUSE

This problem occurs because the functionality that is provided by the Office 2003 component, Web Client service, is not included in Windows Vista. Like Windows XP, Windows Vista only includes a WebDAV client. Based on how the Explorer shell and the WebDav client work when Windows Vista accesses a WebDAV directory, Windows Vista makes OPTIONS and PROPFIND requests to the root of the WebDAV directory. If the root of the directory does not support the WebDAV protocol or the user does not have Read permission to any of the shares in the path to the root, the attempt to access to the WebDAV directory will fail and this issue occurs. The same problem can be duplicated on Windows XP-based computers on which the Web Client service is stopped.
