Cookie does not work in IE

Question

Cookies do not work with IE. The browser allows the use of cookies. It works fine in Firefox ... and works fine in IE when I run it locally. But as soon as I publish, it breaks. It is used for polling, so the user cannot vote more than once. The following code runs as soon as the user tries to vote:

if (Request.Cookies["Poll"] != null && Request.Cookies["Poll"].Value == "Voted")
{
    // Display label
    lblVoted.Visible= true;
}
else
{
    // Update DB
    // Add cookie
    Response.Cookies["Poll"].Value = "Voted";
    Response.Cookies["Poll"].Expires = DateTime.Now.AddDays(30);
}
