Cant connect to WebDAV Share

Hi guys,

i want to connect to Windows Sever WebDAV Share.

I can connect to it with my Windows Computer without authenticating myself.
Does anybody have an idea why i am recieving an “Unauthorized”-Exception when connecting.

In the IIS-Website settings i set the User Option to all Users. The Security-Options of the linked directory is fullaccess to everybody…

I already tried to use the local Server Administrator of my Windows Server, but event that isnt working.

Thank you.
