No resolved host sounds like a DNS issue to me. Might we worth testing that, to see what route your computer is trying to take. It's pretty easy. In the start menu, go to all programs, then accessories, then open the command prompt. In this, type nslookup -type=A mc.villagecraft-server.com. Add a screenshot of this window too.
You could also try flushing your DNS, to force your computer to get a new copy, which might solve the issue. In the same command window, type ipconfig /flushdns, and give it a minute to clear it. Then, try connecting to the server again.
Which ISP do you use? It's possible (but highly unlikely) that they're operating purely on IPv6, in which case we'd need to look into updating our settings.
If nothing works, we can try connecting via the numeric IP instead of the domain, but that's not ideal
