Please follow the below instructions:

  

Step 1: Create a domain account which has the write permission to your UNC share

        Username: yourdomain/admin

        password="admin”

To access resources on a UNC, your application must run under a domain enabled primary secuirty token, the easiest way to do this is to use impersonation in your web config:

 

<identity

impersonate="true"

userName="yourdomain/admin"

password="admin”

/>

where the user name is a domain account with permission to the resouce. all users of

your web site will have the same access permissions to the network resource.

Step 2: create a virtual directory on your Web server and point it to your UNC share folder.
