Hi Daniel, I built libcurl using cmake and the visual studio 10 x64 compiler. I'm new to all this so don't really know how I would have built it with a non-default resolver backend? A quick google points me at c-ares - should I be using that instead?

Thanks Jeff - I get a zonealarm prompt asking for permission when I rebuild & run my program. This only happens when it is working though (i.e. on the main website and not the subdomain). When I get the error message above, I don't get any firewall prompt.

Thanks again,
