vnic0 and vnic1 dns registration problems

Upon installation, Parallels sets up these two virtual nics and they register with our active directory domain under the same hostname as the computer's real name. So if I ping en0, I will get host down because vnic0 or vnic1 has taken over the Mac's hostname. This happens whether there is a virtual machine installed or not.
Is there a way that I can either remove vnic0 and vnice1 or set it to not register with dns? I am using bridged mode so don't need them anyways. It is for Mac Parallels Version 6.
Thanks for any help.
