SYMPTOMS
On a Windows Vista-based computer, you try to access files on a Web Distributed Authoring and Versioning (WebDAV) site that uses only Digest authentication. However, the process may fail after you are prompted three times for your user credentials and password.
If you use a network trace when this problem occurs, the network trace may indicate that the WebDAV server generates a code 401 (Authorization Required) error.
Back to the topCAUSE
When the WebDAV client in Windows Vista sends an OPTION request, the client expects an authentication required message back from the WebDAV server. However, some WebDAV servers do not send this message. Therefore, the client is not authenticated.
