How to fix WebDAV problems with Vista and XP SP2 client

On Windows Vista and Windows XP Service Pack 2 (SP2) or a later version of Windows XP Micrsoft has by default disabled Basic authentication in the Web Distributed Authoring and Versioning (WebDAV) Redirector.

Both Explorer View Internet Explorer, Windows Explorer and the Windows shell commands using the WebDAV redirector will fail if the server is configured to use Basic authentication.

To reenable WebDAV on Vista client

Open registry editor and go to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters

Add a new DWORD Value named UseBasicAuth and give it the value 1.

To reenable WebDAV on XP SP2 client

Open registry editor and go to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters

If a DWORD Value named BasicAuthLevel exists change its value to 2. If it is not found add a new DWORD Value named BasicAuthLevel and give it the value 2.

Possible values for BasicAuthLevel are:

• 0 - Basic authentication disabled
• 1 - Basic authentication enabled for SSL shares only
• 2 or greater - Basic authentication enabled for SSL shares and for non-SSL shares

Another option would be to make server run SSL. It would work with Vista but not XP SP2.
