Trying to implement RADIUS on server 2008 R2 in an SBS 2008 environment

Hi all,

Im trying to implement NPS with a RADIUS client and certificate authentication. Based on the various guides out there I think I know what the issue is, but I cant see how to overcome it. Being in an SBS environment but running NPS on a 2k8 R2 server, the authentication method is looking for a certificate from the 2008 server. But the CA role is installed on the SBS server and so I cant see how to overcome it. What is the best method for me to overcome this?

Thanks
