Deployment of ATL Server project (C++ ISAPI) in Windows Server 2008 and IIS 7.5

Hi. I have a very simple "Hello World" project written in C++ using ATL Server with VS2005, that is working fine in Windows Server 2003 (32 bits). But now I cant't deploy it to Windows Server 2008 R2 (IIS 7.5). The job is to connect to my server (using terminal service) and adjust the server to work properly, interpreting correctly the server response files and the dll created by the project. Thank you.
