Configure certificates for an L2TP/IPSec VPN

so i used this handy: Configure IT Quick: Configure certificates for an L2TP/IPSec VPN (at http://articles.techrepublic.com.com/5100-1035_11-1048126.html)

I think i followed the instructions properly, I requested and installed the certificate. Though when i reconfigure windows vpn client to use IPsec, i get an error that says i do not have a certificate.

i might mention that I’m using w2k sbs and XP, so no w2k.

any ideas?

thanks
