cfcookie not working

Our plattform is:

Coldfusion 9.01

Windows 2003

IIS 6

We did not upload any code or did anything on the server. Our site was unresponsive and we restarted the server.

After that we are getting following when hitting the pages that try to accdess cookies, also I can't access coldfusion admin that was running on coldfusion built in server.:

Any ideas?
