Not if you run your own DNS server.

  Do you know any windows dns cache programs able to filter per application sending a query? Is it even possible in Windows to do that? Something that would allow chrome.exe full access, but block all dns queries from svchost.exe process?

    You would need a software firewall for that.( Komodo? ) Not a cache server. Though running your own dns server on top of that would be nice too.

      afaik Windows firewall is not able to block loopback communications, can komodo?. I dont want to give up dns caching, and since I dont know of any way to firewall localhost traffic in windows I figured only way would be in dns caching program itself. So far only way to prevent dns tunneling I can come up with involves giving up dnscache :(. To make up lost performance you could maybe run dnsmasq on the router, or in a virtual machine? or somehow force dnscache to listen on virtual network adapter?
