Reimaged Win 7 PC still cannot ping either domain controller by IP Address, but sees other PCs fine.

OK so this is weird one: I have a Window 7 box that when I went to use it, I discovered that it no longer had access to the internet, but it did see the other PCs on the network. After trying completely different network ports then removing/reading the NIC and using system restore, I decided to reimage it from scratch and deleted the PC's name from the domain. Here's where it gets strange: Even after a completely wiped and reloaded PC from a known good template, it DOES get an IP address from DHCP/DC/DNS server (same machine) it can view the other workstations on the domain, but it cannot even get a ping reply back from either of our 2 domain controllers, much less join the domain and it still does not see the internet. This one really has me kerfuffled! It is the only PC with this problem and I've already scorched the HD.
