There are multiple symptoms that can arise when there is no root site in a SharePoint Web Application.
These errors are caused by not having a root site in the SharePoint web application.
For example, you have a site at http://www.contoso.com/sites/Test
(http://www.contoso.com/sites/Test), but there is no site at http://www.contoso.com
(http://www.contoso.com/)(the root of the web application).
This happens because the above-mentioned scenarios (and many others) depend on web service or other RPC calls that get made to the root of the web application. If there is no root site, these calls cannot succeed.
Create a root site for the web application:
1. Go to Central Administration | Application Management | Create Site Collections.
2. Select the problem Web Application (Example: SharePoint-80)
3. For the URL, set it to http://<YourHostName>/ (Example: http://www.contoso.com
4. Make the other site collection settings as needed and click ok.
In a network trace, a WebDAV OPTIONS request on the root site ("/") was sent from the client's WebClient (UserAgent: Microsoft-WebDAV-MiniRedir/6.1.7601) to the server:
WEBDAV:Request, OPTIONS /
The server responds with a 404 (Not found):
WEBDAV:Response, HTTP/1.1, Status: Not found, URL: /
Having a web application with no root site collection is not supported in SharePoint. See the following KB articles for more details:
