Guest Peter Herijgers Posted February 5, 2008 Posted February 5, 2008 Hi All, I have a computer (PC1) which is connected to a Server 2003 standard computer. Now I want to make a VPN connection between a client (somewhere on the internet) and PC1 not to the Server2003. If I use PPTP everything is working fine. But for more security I want to use L2TP/IPSec. If I want to make a connection with a client computer to the PC1 I am getting a message that I need a certificate. Both computers, client and server (in this case by server I mean PC1) have certificates from the server2003. That is Root certificates and user certificates. I think I need an IPsec certificate for the client computer to establish a connection to PC1. Is it possible that the Server2003 can generate such certificate? According to the TechNet website only the Enterprice version of Server2003 can generate such certificate. If I use the Certificate Authority on the Server2003 right clik on Certificate Templates and select Manage I notice I have a template for both IPSec and IPSec (Offline request). I can duplicate them but I cannot install them into Certificate Templates for my Root CA. If I go to http://myserver/certsrv and Request a Certificate, click on advanced certificate request, Create and submit a request to this CA I can only select a Basic EFS or User certificate Template. Any Ideas how to create a L2TP/IPSec certificate for a VPN connection for WinXP Pro? Thanks in advance.
