802.1x with VISTA

Hi,

i'm using a Wireless network - WPA2 with AES + 802.1x- CA server and IAS

server.(the CA and ISA are on the same machine).

i'm using windows XP to log on on DELL laptops with intel WIFI client with

no problems at all. (i've deployed computer certificates to all computers

trough GPO...)

i have a few Windows VISTA but i can't log them to the secured WIFI network.

i can see on the IAS event log that the vista system is sending user

certificate and no the computer certificate. i tried all king of things on

the vista workstation but with no success.

any ideas?

thank you,

yaniv.
