WebDav error 401-Unauthorized , Cognos 10.2 ISS-7

[chakra.cognos]

I enabled WebDav in IIS-7 and did the "Add authoring rules" set it to all users.

Wen i opened a image in report studio, and browse for a image, its giving me error as following,

Web server error:

Web server failed.
401- Unauthorized
//serverURL/samples/images

Any suggestions?

You need to install Webdav in web server.
