How to disable the network authentication in my website?

Question

Hi sir,
   I create one website, which plays audio file in gridview , i store that audio files in the server d drive of  192.168.100.4\Recording folder . If i run my application, it is asking for usename and password to display the audio file in gridview.


[Note: If i run the website having gridview containing audio files, it is asking for authentication, how to remove that authentication. I stored the audio files in another machine, so it is asking for authenticatin everytime i run the code]

I attached the screenshot and code for your reference. Kindly give me the solution for this problem.
