Hi, I am struggling to get IPSec access from a Windows 7 client. On the server, I have - a self-generated CA cerificate cacert.pem and a private key cakey.pem - a signed certificate warrior1-cert.pem and a private key warrior1-key.pem I managed to import the cacert.pem as a new trusted root CA in Windows 7 using mmc and this: http://technet.microsoft.com/en-us/library/cc754841.aspx I just don't know where to put the warrior1-cert.pem. When I connect a VPN configured with http://kb.iweb.com/entries/22375983-Configuring-new-VPN-L2TP-IPSec-connectio... it tells me: "Error 766: A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate." I fiddled around a bit with the mmc, putting the warrior1-cert.pem into the "Private" collection of the machine, or let it choose the store "automatically" but I haven't had success. What are the missing parts? If I have done it, I have to do the same on XP..:-( If someone has it working please let me know how. Thank you Peter
