All tcp ports open?

I am not sure what is doing this, but I assume it is a software (or some
kind of) firewall/hids, can anybody point me in the right direction?

I am pen-testing a Windows webserver, and a port scan reveals ALL tcp
ports open. hping also confirms that a SA is returned for any S packets
sent to any port I try. I can connect via netcat any of the ports, and
send data, but nothing is returned. In order to verify services, I am
required to connect and check for a banner or send appropriate protocol
commands to elicit a response.

Has anyone seen this, or have any idea of what this is?

Thanks.
