permissions in IIS for asp.net local website

Question

Hi guys i want to create a website[local] and one of its abilities must be taking screenshot from desktop (desktop of pc where IIS is running, totally i mean server side desktop), you should say why serverside , answer is , i want to see my desktop from my mobile device when im downstairs to see if downloads are finished or not :D

I use this code in asp.net page in codebehind

    int screenLeft = SystemInformation.VirtualScreen.Left;
    int screenTop = SystemInformation.VirtualScreen.Top;
    int screenWidth = SystemInformation.VirtualScreen.Width;
    int screenHeight = SystemInformation.VirtualScreen.Height;

    // Create a bitmap of the appropriate size to receive the screenshot.
    using (Bitmap bmp = new Bitmap(screenWidth, screenHeight))
    {
        // Draw the screenshot into our bitmap.
        using (Graphics g = Graphics.FromImage(bmp))
        {
            g.CopyFromScreen(screenLeft, screenTop, 0, 0, bmp.Size);
        }

        // Do something with the Bitmap here, like save it to a file:
        MemoryStream ms2 = new MemoryStream();
        bmp.Save(ms2, System.Drawing.Imaging.ImageFormat.Jpeg);
        bmp.Dispose();
        IMG.Src = "data:image/jpg;base64," +     Convert.ToBase64String(ms2.GetBuffer());
        ms2.Dispose();
    }

when running from visual studio , its ok , it takes screen shots, but when i published website to local host its showing this error

Server Error in '/' Application.

Answer 2

My first reaction was to say, it's not possible, but since you managed to do that in VS, may be it is..

To setup the user, in the IIS you need to go to Application Pools -> right click on the application pool that your site is using (by default it's ASP.NET V4.0 Integrated) -> Advanced settings -> find the setting called Identity, click on the [...] and then in the new popup click the radio button Custom account, and set your user account there.

If that doesn't solve the problem, I don't think anything will
