ACS 3.3's certificate for Vista

[derict]

Hi,

I am using NAC with ACS 3.3 at backend for authentication. However, the certificate generated works perfectly for XP but not in Vista. I've tried searching around on whether this is compatible but failed to get any idea. Any know if we need to upgrade the ACS version or just update some patches either on the ACS server or Vista machine??

Double-check MSCHAPv2 is selected in ACS Global Authentication settings. I had issues with VPN's on XP compared to Vista because of this.

I've just checked on our setting.Both Allow MS-CHAP Version 1 Authentication & Allow MS-CHAP Version 2 Authentication is selected.
