Webdav mystery -- 301 error on a valid address

[gevermalc]

301, "Moved Permanently"

The HTTP response status code 301 Moved Permanently is used for permanent URL redirection, meaning current links or records using the URL that the response is received for should be updated. The 301 response from the Web server should always include an alternative URL to which redirection (see http: // net-informations com/q/mis/redirect.html) should occur. If it does, a Web browser will immediately retry the alternative URL. This is the best way to ensure that users and search engines are directed to the correct page. The 301 status code means that a page has permanently moved to a new location.

Could you ask your provider what WebDAV client they recommend? And then try to access the server with that client? There probably IS a problem on the server...

One more thing: If the server is using CPanel, the WebDAV server will listen on port 2078. You will have to enter it like this
www.yourservername.com:2078/subdir

I realized I should have posted the resolution:

Poorly designed system, it should have given a 401 or a 403. I finally figured out that it only works at a sufficient service tier.
