a problem with using EAP-PEAP. I'd like to establish a dialup
connection between
windows XP as a client and windows 2000 as a server . And I want to
use EAP-PEAP for strong
authentication.In RAS configuration ,In Remote Access Policy / Edit
Profile / Authentication Tab / PEAP is selected.BUT when I click on
configure button following error message appear:"A certificate could
not be found.that can be used with this extensible authentication
protocol".both of client authentication certificate and server
authentication certificate are installed on server but windows does
not accept these certificates.

The question is that : what kind of certificate should I have on
server?
