Okay, so nslookup CAN find the host (64.4.31.252) but ping CAN NOT
find the host. The only time I have seen something like this is on
malware-infected servers.

Either way, it's not Xen issue anymore. Xen's networking can pass UDP
DNS traffic just fine (nslookup got the correct result). You might
have better luck asking MS guys why nslookup can succeed while ping
can't find the host, and how to fix the problem.
