IPSec VPN between Cisco ASA and Server 2008 R2

Hi,


I need a site-to-site VPN between an ASA and server 2008R2. I've done ASA-ASA ASA-other firewalls many times before but this is a bit confusing. 


What I usually see for Server 2008 is RRAS. I don't think i need that, it's a site-to-site VPN, so please do not suggest that, there are no remote clients to connect to the Server. 

IPSec Policy is configured on the ASA, I just need a guide that will explain the steps to configure the policy and enable he tunnel between the endpoints. 

Thanks
