I just launched an instance of Windows server 2008 on Amazon EC2.

This instance is in a security group allowing RDP and HTTP. Here are the allowed connections on this instance

"Connection Method" Protocol "From Port" "To Port" "Source (IP or group)" 
RDP                 tcp      3389         3389     0.0.0.0/0    
HTTP                tcp      80           80       0.0.0.0/0

I installed tomcat on this server on port 80. I can connect using rdp to the machine, and, using its local Internet Explorer, I can view the welcome page of tomcat on http://localhost

Now, I would like to see this from outside the amazon network, but when I connect to the public DNS of my instance, something looking like :

ec2-*************.eu-west-1.compute.amazonaws.com

I get no response. Any idea on how to troubleshoot this ?

Have you checked the Windows firewall on the instance?
