c# - Capturing screen shot in selenium

Question

Hi I am not able to capture the screen shot using selenium webdriver . I get "Unable to get window (NoSuchDriver)".It works fine with Firefox. I tried running on User1 then it ran well but when I switched to another User ie(User2) switching User then I get this error

   public string TakeScreenshot(IWebDriver driver, string SnapFolderPath, string TCID,   string      KeyFunction)
    {
        ITakesScreenshot ssdriver = driver as ITakesScreenshot;
        Screenshot screenshot = ssdriver.GetScreenshot();
        string filePath = SnapFolderPath + "\\" + TCID + "_" + KeyFunction + "_" + GetDateTimeforFilePath() + ".bmp";
        screenshot.SaveAsFile(filePath, ImageFormat.Png);
        return filePath;
    }

Maybe it has to do with your internet settings, try this:

Tools > Internet Options... > Security tab, Enable Protected Mode checkbox is at the bottom of the tab.
