Where has the Remote Assistance firewall exception gone under Windows Firewall GPO settings?

Hi,

I need to open up Remote Assistance for my domain workstations and I can't find the option to this via GP.

The machines are running Windows 7.

I can do it locally but it not through policy.

The Remote Assistance predefined rule is missing.

When I create a GPO and go to the firewall settings I can see all the other rules.

But not Remote Assistance.

Is this normal or is it just me?

Thanks
