VirtualBox Name-Resolution Issue

Running VirtualBox 4.2.4r81684 - newest version, as far as I know. Both the VM and the host PC are running Windows 7. It was working at one point, with the virtual NIC set to NAT mode. It could reach both the internal "server" - the host machine - and the Internet, without a problem.

Now, for some reason, it no longer works properly:
In NAT mode, it can reach the Internet by name or by IP, but it can only reach the local server by IP.
In Bridged mode, it can reach the local server by name or by IP, but it can only reach the Internet by IP.

I've tried everything I can think of. The server needs to be able to reach both, by name or IP. I've even tried adding the bloody things to the hosts and LMHOSTS.SAM files. Nothing helps. I've set and unset NetBIOS over TCP. Neither helps.

Does anyone know how to get them BOTH working?
Do I need to use WINS?

in bridged mode, it would seem DNS resolution is not working, does your client have an IP address for DNS, are you using DHCP?

in NAT mode, can you create a hosts file on the vm, with the IP address of the host

So... It turns out that the problem was the Vipre firewall on the host machine. Not sure what changed, but evidently something did - perhaps it was a Vipre update that did it. But I was able to open it up by allowing anything from the VM's MAC address, while the VM was in Bridge mode. So it's working now.
