I just spent six weeks with same issue. I believe a vista update did something to the mac address of the network card as it should not be all zeros. Could not find any way to change until I came across a post suggesting to download freeware Technitium which will overwrite the mac address in the registry. ( back up first in case of problems). I also have HP with Nvidia NIC running vista home premium. ISP eas no help. HP could not figure it out even when I told them about the physical address issue.

a mac address is burned into the nic physically. the only override for this is in the nics properties and "locally administrated" which is usually blank.

Some bios's will list the mac address of the builtin nic. If a card you can get the mac using that cards utilities if they exist. Otherwise you can pull the card and the mac is written on the card.

I would suspect malware not an update

did you search the registry for "MAC"? Match case needs to be checked in Find and capitalize MAC. Mine are listed [wireless/wired/virtual]
