Host checker to Deny Wundows XP Access

[ntl75]

Hi
I want to be able to deny Windows XP Clients. I have tried adding a custom policy based on HKLM Software\Windows NT\Current Version but when I check the logs there is no check on OS.

What am I doing wrong.

many thanks in advance

Have you tried creating a host checker policy using the pre-defined OS check rule selecting all but XP?

I did initially try the predefined rule and that didn't work but I have managed to get it working now.
many thanks

What did you end up doing in the end to make it work?

... and Did you end up using the predefined rule or a custom, etc?

I'm using VPN Tunneling Access Control policies to restrict clients based on the OS in the user agent string.
