    Cookie is stored by a browser only on direct request of the web server to do
    so, that is, client connects to the server (to port 80 I guess), then
    receives a reply - headers plus body. One of headers is used to create a
    cookie. So the only way a cookie can be introduced is by web server. So
    either your whole installation is compromised, or, much more likely, there
    is something misconfigured on your IIS.

    Simply use netcat/telnet to connect to the server and check the headers
    sent.
