Sometimes.... very rare, the NIC information in the registry gets all borked up. This occasionally happens on physical as well. One trick is to nuke the NICs and do over. If that doesn't work, there are three different places in the registry that store this stuff regarding NIC information and static IP Addresses that will have to manually addressed/cleaned up. I am sorry I am being a little vague but this has only happened twice to me and we sort of 'felt' are way through it with a few web searches, registry searches and experimentation. The last was about 2 years ago (co-incidentally during a VMware upgrade :)
Hope that helps some, if not hope you don't follow the rabbit hole down to far.
