XP Pro, service pack 2. Fresh off virus and spyware infection, AND a windows repair, I have a NIC that is built into the motherboard, which will not connect to the network unless I disable the network adapter, then enable it. Then it willl be fine for a few hours, or until the next logoff / logon. THEN (once again) it shows "limited or no network connectivity." ----UNTIL, you disable and re-enable the card.
How do I get this thing to just stay enabled and behave?
