Remote Desktop limit to countries

Is it possible to limit Remote Desktop to some countries (and not just ips)

I am sure this is not some thing that is possible from within remote desktop but with some scripting. I dont want my remote desktop to be accesible from countries where I don't travel to or have any business with (which means any thing beyond Western or Northern Europe is probably not me)

I am asking this for Windows 2008 standard server.

Why don't you look into some sort of VPN?

Operating on a non-standard port would also help, though security through obscurity is never terribly effective.

You could setup a firewall to block IPs from certain countries, but there's no way to guarantee where the originator of a packet it (they could us proxies or a myriad of other technologies).
