WebException: The remote server returned an error: (401) Unauthorized - Sharepoint

I got this error when accesing an xslt file. Here is the code. I get the above error at
"xsl.Load(xslURI) ". This is SP2013 and it is my vm box. I have administrative privelages. Looks like to me a security issue..


 Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
            Dim xmldoc As XmlDocument = New XmlDocument()
            Dim web As SPWeb = SPContext.Current.Web
            Dim list As SPList = web.Lists("Test")
            Dim li As SPListItem = list.GetItemById(CInt(Request.QueryString("ID")))
            xmldoc.LoadXml(li.Xml)
            Dim xslURI As String = web.Url & "/SiteAssets/TestDisplay.xsl"
            Dim xsl As XslCompiledTransform = New XslCompiledTransform()

            xsl.Load(xslURI)  
            Dim sb As StringBuilder = New StringBuilder()
            Dim sw As System.IO.StringWriter = New System.IO.StringWriter(sb)
            Dim xmlw As XmlTextWriter = New XmlTextWriter(sw)

            xsl.Transform(xmldoc, Nothing, xmlw)
            Server.HtmlDecode(sb.ToString.Replace("~siteurl", web.ServerRelativeUrl), writer)
        End Sub
    End Class

The account that is running your application pool need to have access to the .xlst file you are trying to access remotely.

Are you using default networking service account for your application pool? you might need to create an account specific for this.

I'm using administrative account for the app settings. I changed it to use local system but still get the same error.

Sorry for not back to you before now.

Is the file you are trying to access on the same server? If not you have to grant the access/permission for the account where the file is located.
