i set up remote access VPN connection from windows server 2003 against ASA 5520 using a pre-shared key. I used a L2TP over IPSec method. This work fine, when i use a md5 authentication, but as i found Windows 2003 is not working with SHA authentication.
But when i use a Microsoft Windows7 client to conect to ASA it is not working aganst md5. In ASA logs is statement "All SA proposals found unacceptable". I found that is a problem with authentication but changing to SHA is not working too.
Have someone idea how to configure ASA and Microsoft windows 7 client together?
