2 of my clients have had this happen in the last 36 hours.
After a full drive scan and discovery of many un-repairable Trojans that had to be deleted XP and the computers NIC will no longer communicate. I can go to another computer and see the MAC address through the router, but when you check the status of the NIC all you see is a low number of packets sent.
Does 4.6 remove something that it should leave alone?
Any help / suggestions / advice is appreciated
